Blogs are all about web development, software development, mobile apps development, cloud computing, artificial intelligence, machine learning, golang and so on. Recent upgradations in technology that you must know.
Golang- Go programming language is highly swift and seamless to use. It has been the talk of the town since its early outbreak and is becoming stardom of high performing software development. When you use Golang, you are entering the software era of huge possibilities.
Still young entrepreneurs are hesitant to use Go. They are not aware of why to use Golang, how to start with Go development and when to use and avoid using golang for your business. So here we came with some facts, benefits of the Go programming language. Let us see why, when and how to start with Golang for your software development project.
How To Get Started With Golang?
Go programming language is the most adaptive programming language based on the syntax of C and equipped with the enhancement on the dynamics of safe managing the memory use, static typing with benefit of concurrency and managing objects optimally. Golang offers app development with speed, highly accessible development tools, fully stable & concurrent & above all awesome Go community support. Here are 3 main goals of Golang-
Simplicity was the main goal of creating the language and is achieved. It has a very simple syntax so developers can develop apps faster than other languages. Golang can be easily learned by beginner, even though someone who does not know any programming language but wants to become a developer, he/she can. Go is as easy as PHP but as powerful as C++. The syntactic developments in Golang are somewhat pitiful; there is no undeniable OOP implementation. Go is a functional language that can be used to solve problems of any level of complexity, including those needed by businesses.
2. No External Dependency For Your Project-
With the programs written in Golang, one can produce native binaries. Having external dependencies for software development projects, you have to depend on other source codes or binaries. Best thing about golang is you can create a native binary within your project and use according to your way. It is that much easy. There is no need for external dependency for your project. Deployment of Go app is like copying a complete app file to the destination server.
3. No Classes, No Inheritance-
Golang doesn’t have the whole structure of classes and inheritance. Which means that app development is a lot simpler for developers because they have code in one window and one class or in one editor.
4. Highly Flexible-
Golang is an open-source programming language with great flexibility scale where developers can easily make changes into it and even expel aspects you think shouldn’t be there.
5. Go Is A Concurrent Language-
Golang is so intuitive. It is great for beginners because they can do various things at the same time easily. Most production software systems need to do lots of things all at the same time. While other languages mostly have mechanisms to do this, they can be complex, slow or result in buggy code. Go is mostly recognized by the developer community as a leader in simplifying concurrent apps.
According to the study, it has been revealed that an average mobile user has around 36 installed apps but regularly uses just 9 of them on daily basis. Generally users get impressed by good ux design and it leaves a long lasting impression. So the difference between a successful mobile app and one that fails in the market is quality user experience(UX). UX involves everything that affects user’s perception and interaction with app. Without detailed understanding of the target user’s in-app behavior patterns, you cannot build a mobile product to fulfill a specific goal or exceed expectations. So it is important to build or improve great UX of your mobile app to succeed. Here we’ve curated ten different strategies to implement to implement throughout the lifecycle of mobile app to continually achieve great UX.
Main goal of onboarding is to show the value of the app to the user, by demonstrating how quickly and efficiently they can get what they want. If user face any trouble within a few screens, they’ll go back and uninstall the app. Hence, providing great onboarding experience is important to attract and retain users. According to the survey, it has been noticed that, within the first week of downloading an app user retention already drops by 25%, but implementing efficient onboarding, an increase of 50% in-app user retention was noticed.
You can integrate some strategies to maximize UX during onboarding phase to encourage users to come back such as tutorials showing how the app works. Ideally this kind of progressive onboarding is used if the application has a complex workflow or hidden functionalities that the user may not be aware of right away. You can also, reduce the number of steps required for account creation/signup, and include multiple registration option such as sign in with google or facebook.
2. Create More Interactive Designs-
If you want user to love your app designing skills and increase engagement, then your app design must be highly interactive. Because of interactive design, app designers pay attention to developing eye-catching web interfaces using logical and creative imagination in the process. Also, users always expect something new and trendy in app design they use, so it is necessary to use latest trends and techniques to achieve the desired output.
3. UX Design Compliments The Battery Life-
Most users complain that some of the apps tend to consume a lot of their phone battery and so it drains out too fast. Users are very careful about their battery and would uninstall your app immediately if it is getting exhausted very quickly. Hence you must ensure that you rapp does not consume much battery along with other important resources like data and memory.
4. Animate Your Transitions-
Animated transitions are effective way to create seamless flow when moving from one page to another. Here are some of the key practices for effective animation implementation:
Animation should be used in a way that user can understand how to complete an action.
Don’t have animation without prior user action.
It is fine to have one or two animations in the app. Don’t overload animations.
5. Personalize The UX-
Personalization provides a unique and relevant experience to the user. Wherever possible, personalize the UX by using user data to display relevant content and material in the app. For instance, provide users with particular retailer deals according to their location. More aligned the experience is with a user’s requirements, the more likely they will continue to use the application. Including the user’s name on the screen and in messaging is an easy and effective way to personalize. Implementing lots of push notifications or pushing irrelevant content will irritate the user. Ensure that you display only hyper-relevant content to each individual user for the best results.
Creating any project is an overwhelming task in itself, yet modern technology can make the development process less painful. Before you start development it is important to choose an appropriate platform. Lots of developers might get confused to choose between React and Next.js. So here we’ll go through the comparison of React vs Next.js. But before this, let’s have a look at an overview of react and next.js.
What Is React?
React was created by Facebook and now it is one of the most popular javascript frameworks. It is trying to set industry standards. Now, every react development company suggest using a receptive methodology and functional programming paradigm which makes ReactJS more of a library and less of a framework. So, the need for creation of your own workflow increased and that workflow is now called Next.js.
React includes various components, and each component has its own logic and controls. These components are responsible for rendering a small, reusable part of HTML that can be reused wherever you need it.
Has great documentation, tutorials and training resources
It supports various tools and so has gained huge popularity.
What Is Next.js?
It is a framework developed by Vercel and is an open-source dependent on Node.js and Babel and coordinates with React to create single page apps. This eases the server side rendering. Also, Next.js supports static export, pre-delivering and has great features like programmed building size optimization, quicker developer aggregation and a preview mode. Latest version of Next.js that React has been missing for a while. It has all the usefulness that you might need for app development. Also, there is a great documentation and it’s getting popular with front-end designers.
Advantages Of Next.js-
Very simple to set up- Though CRA setup is somehow tricky, Next.js eases it by allowing you to add Webpack loaders or Babel plugins.
Ability to use API routes- While bundling app with third-party APIs, you need native API, and Next.js eases it to build. Next.js offers API routes.
Applications built with Next.js are fast because of static site creation and server-side rendering.
React Vs Next.js–
1. Speed And Easiness Of Coding-
Consider that you need to make pages for React project, you have to make a segment and then add it to the router. Assuming you need to make pages for Next.js project, you just add page to the pages folder and necessary header component link. This eases your life because you write less code and the project is not difficult to follow.
If you’ve started using React, creating React app is an extra method to learn it. The CRA gives you an early advantage assuming you need to use React to create a single page apps. In the comparison of React vs Nextjs, creating React app is just liable to make front-end assembly, you can use it with a server of your choice such as Node. You must know that CRA uses Babel and Webpack in the engine, but no information is needed about them.
Create react app tool saves you the issue of setting up and changing your development environment. Just simply run one command that will set up the tools you want to run your React project. So instead of wasting time on customization, you can focus on app development.
2. Configurability-
Simple difference between React vs next.js is that React does not have a space for configuration. You cannot change the configurations unless you stray away from the normal CRA. You need to use what is already configured in the read-scripts of CRA.
With Next.js all things are configurable. You can configure files such as balelrc, jest.config, eslintrc and so on from the NextJs templates.
3. Features-
React is easily extensible and can include features such as routing and state management patterns with libraries like Redux. It is minimal but can be customized for any project.
Next.js has amazing features like- server side rendering, static export(SSG), Pre-rendering, automatic build size optimization, faster development compilation. These features are there to help you in creation of workable and ready-to-go app.
4. Performance-
Main difference between React and Nextjs is its performance. Application developed with Next.js are very quick by virtue of static destinations and server side delivering. Definitely they are viable because of the performance enhancement features, for instance, image optimization presented in Next 10. So if you choose Next.js, you get a benefit form automatic server rendering and code parting. Also, SSR(Server Side Rendering) will work on the performance of your app.
For react, there are things that rule it out of the discussion. It supports client side rendering, that is not sufficient assuming you need to assemble an high-performance app.
Best React Native UI Component And Animation Libraries
User interactions and engagement are important for the success of mobile apps. So developers need to create attractive user interfaces and use animations. Users love using animations while using an app, this improves user experience to the next level. Same thought also goes for react native app development. Well designed UI and animations helps to improve user engagement within an app. So developers should use the UI component and animation libraries while working with the React native platform.
If you are going to develop a mobile app, using react native UI component and libraries will help you to provide more attractive user interface. Let’s have a look at some popular react native UI component and animation libraries to use in 2021.
It is a cross-platform React Native UI toolkit that collects all in one place a number of great open source UI components made by developers. You can get into the packages put together by React Native elements and ensure that the API has a consistent look and feel. It has received 17000 stars on Github. Package includes a whole basket of components like pricing, badge, overlay, divider and platform-specific search bars. They are very easy to use and really customizable.
The props for all components are defined in one central location that makes it possible to easily modify and update components. Also, it can serve as a platform connecting small teams developing commercial React Native apps with open source contribution. There is a React native web to use react native for your web-based projects. It allows for creation of fast, adaptive UIs in javascript and integrates with react Dev tools. Developers can share codebase between React Native apps and web apps. It supports type, click or swipe as modes of input has built-in accessibility and RTL support, and is used by likes of Twitter, Uber and Flipkart.
2. React Native Paper-
It is a cross-platform, open-source library that provides more than 30 production-ready and customizable elements that follow the material design rules. It provides support for both light and dark themes. Also, it allows you to seamlessly move between distinct themes. If you have selected the theme, simply use the Appearance API of React Native for applying theme moving based on device settings. Paper also allows developers to add easy, clean and simply customizable UI elements to your development immediately, hence you can be ensured to get the remaining MVP in place.
3. Nativebase-
For new React Native developers, NativeBase is good to start app development. Some open-source projects Nativebase library include a tutorial app, a Twitter Clone app and Native starter app.
NativeBase is popular to offer mobile-first and accessible elements. With this library, you can create and maintain a stable design framework across both web and mobile platforms. Also, it provides a list of elements for React Native UI development. NativeBase supports accessibility with React Native ARIA and themeable design systems that are optimized for light and dark modes. If you want toast for elements and advanced elements like row, skeleton and column for layout with important elements such as icons, overlays, flex, checkbox and buttons, NativeBase for helping developers to create customized UI elements.
4. React Native Camera-
This great library helps to communicate with your device camera. It allows you to use some easy functions without thinking about the native code. The camera element of React native supports barcode scanning, face identification, photographs, text recognition and videos for ios and android.
5. React Native Snap Carousel-
It allows some ways to show a bunch of photos in a gallery view. Carousel is a popular technique to do the same. It offers multiple layouts, previews, performant management of a significant number of products, parallax images and so on. Carousel is compatible to android and ios. It helps user cycle through a collection of images that can be shown horizontally and vertically.
Shortly, it helps developers to their content on various mobile devices. While using stylish carousels or sliders in your app, go with React Native Snap Carousel. This UI library includes lots of tips that help in performance optimization; it is well documented and contains some other useful features also. Snap Carousal contains a wide API comprising property and multiple plug-n-use layout patterns. It also allows developers to execute animations and customized interpolations.
7. React Native Gifted Chat-
Gifted Chat has more than 8k starts on Github. It helps you to set up a Chat UI for React Native (and web). It is written with TypeScript and includes completely customizable components which help to load earlier messages or copy messages to clipboard and so on. InputToolbar helps users skip the keyboard. To improve user experience, it allows Avatar as user’s initials, localized dates, multi-line TextInput, quick reply messages (bot) and system message. There’s support for Redux too.
6. Bit For React Native-
It is not a library but a great tool that you can use to create component-driven applications. Bit is useful for systems that are easier to understand, simpler to collaborate, quicker to build, and easier to maintain. You can use it to track elements and export them to virtual monorepo of Bit, i.e. Bit.dev. This makes each element accessible and usable for other projects also.
Programmers can independently create and maintain them as per their need. Also, they can remove or add elements from apps to modify their functionality also. With the Bit, they do not need to establish a dev environment to make some changes.
The Best React Native Animation Libraries-
7. Lottie For React Native-
This library from Airbnb helps you to add animations to your apps. Generally, after creating animations in Adobe after effects, you need to convert them into a format usable in your web app. And lottie help you with this. It works by reporting animation data in JSON format from an After Effects extension, BodyMovin. This extension is packaged with the JS player to render animations on the web. It works with React Native also, and you can access the official docs on Github where it has received 12k stars.
Lottie libraries and plugins are available for free and you can use the collection of animation files to make your apps attractive. Animation files are small in size and are in vector format. As such, you should not experience any impact on the app’s performance. Simultaneously, it can improve your UI and make it more engaging.
8. Ignite CLI-
It is a solid starter kit for React Native apps. Default React Native boilerplate helps you to build native apps. It installs and clings to best practices in its construction, while permitting you to adjust the boiler plates to your project. It works with both ios and android. There’s support for standalone plugins also. Modular plugin system allows you to add app features or write your own. Usage example screen helps you to test third-party libraries and build apps consisting of multiple components. Screen contains examples of common apps built by using fundamental components. So as to help you, identify the components and make changes to them easily, this screen also registers the examples in the component’s files.
9. Pose-
This react native animation library allows you to make animations seamlessly. It chooses animation automatically according to the mentioned property’s name. Also, it supports unmounts and mounts animations and gestures such as React element.
10. React Spring-
It is very simple to use a cross-platform animation library that supports react-native-web, react native, web and other platforms too. React Spring has its API available in a pattern of plug-n-play React Hooks. This library covers most UI animation requirements. If you are looking for casting your concepts into moving interfaces, you can go with it. React Spring brings modern animation methods and it connects both declarative and imperative react motions.
11. Fluid Transitions-
This library is used to execute some fluid transitions between components. It can be implemented while navigating with the React Navigation library. It executes a new navigator- Fluid Navigator. This Navigator overrides StackNavigator from React Navigation. It shares similar API and configuration procedures such as navigator from the navigation library. Also, it helps in customizing transitions and facilitates gestures for navigation. This library does the shared transitions between similar elements when each element has a placed to different navigating screen.
12. React Native Flip Card-
Basically this library is a card element that includes a flip motion for React Native in iOS or Android.
13. React Native Motion-
This library is used to create animations in React Native with easy to use features. It also provides a simple API to make shared transitions.
Angular is a popular web app development framework led by the Google team and community of individuals and corporations. Recently on 5th August 2021, Angular came with its new version which is Angular 12.2. Version 12.2 has major changes to the core and compiler of the framework. Let’s see which are those.
What’s New In Angular 12.2?
1. Forms-
There are some updates in the core of the framework like the form. The form in Angular version 12.2 has got a lot of attention with expansion of addValidators, hasValidator and removeValidators methods. You can also expect, they allow adding and eliminating a validator or a variety of validators to/from a structure control, group or array. As of now, you need to wipe out all validators and reset them when you want to add/eliminate one, which was not good for normal use-cases like making a field required depending upon a condition:
//frequency is required if auto-refresh is enabled
{
if (isAutoRefreshEnabled) {
this.autoRefreshFrequencyCtrl.setValidators([frequencyValidator, Validators.required]);
} else {
this.autoRefreshFrequencyCtrl.setValidators(frequencyValidator);
}
this.autoRefreshFrequencyCtrl.updateValueAndValidity();
});
With the new Angular v 12.2, simplification of such code is-
These techniques have a form for offbeat validators with hasAsyncValidator, addAsyncValidators and removeAsyncValidators. Just one thing to note that hasValidator/hasAsyncValidator techniques works just with a reference to the specific validator function, hence it doesn’t work for example:
this.autoRefreshFrequencyCtrl = new FormControl(10, Validators.min(5));
this.autoRefreshFrequencyCtrl.hasValidator(Validators.min(5))
// returns false
Same for removeValidators/removeAsyncValidators because they use hasValidator/hasAsyncValidator within the structure.
2. Split two-way binding checks-
Next feature is using strictTemplates, regular two-way data binding does not pass type-check anymore. From Angular 12.2 onwards we don’t have to retain the data the kind of the value alloted through (xyzChange)=”prop = assignedValue and rather trust it to be the generic Event type.
3. Templates-
As ES2021 is considered in Javascript, recent release Angular 12.2 the compiler supports underscore as separator for numbers in format. You can write-
{{ 1_000_000 }}
4. Faster ng build with esbuild-
Next new feature of Angular 12.2 is new CLI which supports esbuild that makes compilation and building of angular applications more rapid. Angular CLI 12.2 uses esbuild to optimize built code, in collaboration with terser. However fast esbuild is, it doesn’t cover all optimization like terser. Now that CLI is optimized, the code runs in two phases- one on esbuild and other on terser on optimized code from esbuild.
Esbuild is used to optimize the CSS of component stylesheets. As it is faster than CSSNano, it generates smaller outputs. Though the global stylesheets continue to be optimized, it might migrate to esbuild in the future as well if it is supported by sourcecap.
5. Sass Deprecation Warnings-
If you’re using the scss style, you might have seen that dart-sass(that the CLI uses in the engine) shows alerts for Sass documents that are using deprecated/operator. Moreover, it yields a ton of alerts. The community is using Font Awesome in some projects, and the CLI is logging many lines. Another great news is that CLI v12.2 covers the warning for third party stylesheets. You can see them with the – verbose flag.
Lots of developers use Angular for effective web app development. So upgrading with the latest version, you can use amazing new features of latest v12.2 for development. If you’re thinking of building a web app, consult with Solace experts. We are here to help you through consultation and development.

Code quality is an important and popular term among software developers. Mostly software quality is attributed to an intuitive user interface, detailed testing and security. But the main aspect is code quality which is mostly neglected. This raises a question that- what is code quality, how to measure it and how to maintain throughout the software?
So, here we’ll discuss answers to all these, but before that, you must know that bad code quality can create issues in software that may restrict you to do some improvements that clients would like to see. For instance, your current application is working well but you want to add more features. When developers observed the app code, they reported that the code can’t be refactored. If a developer still goes ahead with adding features in the same code, it will create issues in your existing software application. Then, you have to make changes in the plan of feature improvement or start the development from scratch. If you want avoid all this, improve the code quality and maintain it throughout the software development. Let’s have a look at what is code quality and how to improve it?
What Is Code Quality?
Code Quality
Code quality refers to the usefulness and maintainability of code in the long term. It covers both great and bad quality code. Basically, it provides insights to the project managers about the coding practices and style followed by developers. Different teams might use different definitions according the context.
Importance Of Code Quality-
1. Increases Readability And Ease Of Editing-
Good quality code ensures that the codes are written in a way that makes them highly readable. Some of the factors are using proper comments, indentation, clear notations and simplicity. Code editing is more comfortable with high-quality code because they are easy to read and implement changes.
2. Making Program Sustainable-
Software is supposed to be sustainable when it can survive over the long run with insignificant changes. Average software life is accounted to be around six years, but poor software quality doesn’t last even half of this time duration. This is because, with the consistent development of operating programs and hardware, change in software raises. It is challenging and sometimes impossible to perform transformations on the poor code quality.
3. Promotes Easy Transferability-
A high quality code is easy to edit and has high readability. Another importance is that the code quality practices make the straight software translation across platforms easier. With lots of available platforms, it is necessary to have direct transferability with minimal changes required.
How To Measure Code Quality?
There’s no single way to measure the code quality. What you measure may be different from what other development team measures. Here are some of the code quality aspects to measure-
1. Reliability-
It measures the probability that a system will run without failure over a particular period of operation. This relates to the number of defects and availability of software. Numerous fo defects can be measured by running a static analysis tool. You can measure software availability using mean time between failures (MTBF). Low defect counts are important to develop a reliable codebase.
2. Maintainability-
It is a measure of how easily software can be maintained. It relates to the size, structure, consistency and complexity of the codebase. Ensuring maintainable source code depends on various factors like testability and understandability. You can’t use a single metric to ensure maintainability. Number of stylistic warnings and halstead complexity measures are Some metrics you may consider to improve maintainability. Both automation and human reviewers are important to develop maintainable codebases.
3. Reusability-
It measures whether existing assets like code can be used again. If assets have characteristics like modularity or loose coupling, it can be easily reused. Reusability can be measured by lots of interdependencies. Running a static analyzer can help developer to identify these interdependencies.
4. Testability-
It estimates how well the software supports testing efforts. It depends on how effectively you can control, observe and automate testing. One can measure testability based on how many test cases you need to find potential faults in the system. Complexity and size of software can impact testability. Hence, applying methods at the code level- like cyclomatic complexity- can help to improve the testability of component.
Best Practices To Improve Code Quality-
1. Architecture Is Priority-
Most of the people say that they do things very rapidly as they don’t have time to think about architecture. But due to this, 99% of them face a big issue. Writing code withing keeping architecture in mind is a vain. So before you start, you should have complete understanding of what your code will be doing, its uses, how modules and services work with each other, what structure will it have, how will it be tested and debugged, how will it be updated and so on.
2. Use A Coding Standard-
Use of a coding standard is one of the best way to ensure high quality code. It ensures that everyone is using the right style or not. This improves readability and consistency of the codebase. It is a key for lower complexity and higher quality.
How to Do It-
Train your developers
Help them to comply with it
Using a static code analyzer, you can do this.
3. Analyze Code-
Quality must be a priority from the beginning of development. You must analyze the code before code reviews begin. It is better to analyze code as soon as it’s written.
In case of DevOps, code analysis takes place during the development phase. Static analyzers can be run over code as soon as it’s written. This creates an automated feedback loop, hence developers can improve code before it enters the code review phase. All things considered, if you find errors very early, you can solve them rapidly and in an easier way.
One of the best way to improve quality is by analyzing code automatically. By running a static analyzer over code in early stage, you’ll ensure the code that gets to the code review phase is the highest quality possible. Also you can use static analyzers like Helix QAC and Klocwork to monitor key quality metrics.
4. Code Review-
Code review is vital for maintaining code quality and growth of the team. The code of software must be reviewed early and in small parts. Review a 1000 lines of code which would be spanning several subsystems. This is the quickest way to get people either blindy approve or to discourage them from taking the time to review. Smaller changes make it easy to justify taking few minutes to look at code and make constructive suggestions. Also it eases the developers work fo writing the code to implement the suggestions.
Final Words-
Code quality is the most important factor for the success of a software. Try to use better coding standards across your team and company.

Along with Java and C++, Kotlin is a programming language for Android. According to Google, more than 50% of professional Android app developers use Kotlin to develop their Android applications. Meaning that, it is one of the most loved programming languages worldwide. Besides, it is also expected that Kotlin may even change how Java is used on the server.
Means,if you are an android developer or going to develop android app, you must know the Kotlin programming language for effective apps development. The best advantage of Kotlin is lesser number of lines of code. Along with this, there are many more useful kotlin features that you should know if you are going to develop an android app. Here we’ll discuss those important features but before digging to it, let’s see the benefits of Kotlin over Java.
Benefits Of Kotlin Over Java-
Kotlin is designed by JetBrains to overcome the challenges of Java. And hence, gradually it is replacing Java in ANDROID app development. Here’s a list of benefits of Kotlin over Java.
Easy To Maintain- The statically typed programming language support a wide range of IDEs, importantly Android Studio.
Advanced Compiler- Kotlin has a smart compiler. It can detect errors to compile time and perform a check to reduce runtime errors.
Fail-Safe System- As the code is compact, the chances of error are less. Besides, there are some app crashes and system failures incidents with Kotlin.
Interoperability With Java- It has tools and frameworks compatible with Java.
Concise And Clear- Kotlin for android app development is clear, concise and practical. Kotlin extensions are part of Android Jetpack family which helps to optimize android platform APIs, and Jetpack for Kotlin use.
JetBrains has kept its language design clean and made the syntax simple. Besides, it takes very less time to write the code that improves the developer’s productivity. As an android developer, you should know these Top 7 Kotlin features that make android app faster, easier and error-free.
Must Know Kotlin Features For Android App Development
1. Null Safety In Kotlin-
Each Java developer must have been frustrated by NPE (NullPointerException) at some point in time. Special Null value can be assigned to object reference and NullPointerException, a RuntimeException is thrown when a program tries to use object reference that has null value. Exception can prematurely terminate the program. As Java doesn’t provide any information about the object not created by developer has no null value, during the compilation time it put unnecessary pressure on java developer to keep the program null safe.
But when you use Kotlin, no need to worry about this. Kotlin has a null-safety feature at the starting age, that is by determining that values will be assigned to the null factor or not. Kotlin’s compiler is powered by null-safe feature which improves run-time Null Point Exceptions encounters.
2. Lazy-Loading Feature-
Faster loading time is one of the most important criteria for any quality app and Kotlin’s lazy loading feature takes care of this. While using Kotlin for android development, this feature will help you to minimize the startup time for the app. It loads the initial content faster to reduce startup to reduce startup time while slowly leading other less necessary elements and contents down the page. Because of this lazy loading feature, android developers who work with Kotlin can just give the priority to the primary resources and keep them in main memory to ensure faster loading while keeping others or secondary resources in secondary memories.
3. Standard Library Functions-
Developers can use standard library functions offered by Kotlin programming language. It eases implementation of higher-order functions with idiomatic patterns like apply, let, use and so on. Also, it has lost of utilities to work with char and string sequences. Its Extension functions provide query operations for sequences and collections. Kotlin’s JDK classes made working convenient with IO, files, and threading.
4. Data Classes In Kotlin-
The need of a class is always argued by programming language designers/makers. Generally, a data class in java contains huge boilerplate code that developers should skip so as to find out the real use of that class. However in Kotlin, Android developers can write the equivalent of the same Java code very simply with less code. So, data classes in Kotlin are known as one of the useful features.
5. String Interpolation-
String interpolation is done through string literals having placeholders that are assessed to achieve a result where placeholders are replaced with corresponding values. Mostly string handling in Java is difficult, that include the use of plus operators, String.format, and StringBuffer. The simple process of String interpolation in Kotlin becomes complex for Java developers.
Java developers must have an idea of processing object collections that are important in the Java app development process. This happens because Java objects get translated to various presented elements through this process. Mostly this causes a parallel stream of translated objects which results in slowing down the application. As a modern programming language, Kotlin handles this with immutable collections. Here, rich functional APIs will consequently return as the collections are characterized by the unique functionality..
7. Extension Functions-
Extensions of Kotlin are very useful, this is so because they allow developers to add methods to classes without changing source code. Similar to Scala’s implicit methods, in Kotlin developer can add methods on a per-user basis to classes. For instance, have you tried activity has some methods such as Hidekeyboard()? With extensions, developers can do it like this-
