JavaScript vs TypeScript: A Comparison

Read more at-
As we all know that JavaScript is lightweight, interpreted programming language while TypeScript is strongly typed object oriented compile language. When JavaScript was growing, it’s speed became complex and overwhelmed. Due to this JavaScript was even not able to fulfill the requirement of Object- oriented programming language. Hence JavaScript is lagging at enterprise level as a server- side technology. Development team developed a TypeScript to overcome this lagging problem. Lets proceed with JavaScript vs TypeScript.

What is JavaScript?

JavaScript is a scripting language. For the creation of interactive web pages uses JavaScript. It is a light weight language. Purpose of designing the JavaScript is large application’s development and also trans compile to JavaScript. JavaScript is both client-side and server- side scripting language.   

Features of JavaScript-

• It is a cross – platform language.
• For client side and server side, JavaScript can be used.
• It is flexible and also powerful language.
• Framework Unsupported.
• Developer will have a ‘the great freedom’ to do whatever he wants with any object.
• It has a strong Testing workflow.
• JavaScript Added Dependencies.

What is TypeScript?

Microsoft developed and maintains a TypeScript. It is open-source programming language. It is strongly typed object oriented programming language. TypeScript code can be run on any browser, devices or also in any operating system. TypeScript code could not be understand by browsers. Therefore this code need to convert in JavaScript. Now browser can understand this code. This process is called Trans-piled. 

Feature of TypeScript-

• TypeScript offers great productivity for developers also.
• It supports ES6.
• TypeScript supports interfaces, sub – interfaces, classes and subclasses.
• It has rich IDE with autocomplete and also has code navigation features.
• Code navigation and bug prevention is possible with TypeScript.
• Scalable HTML5 client – side development.
• It has class-based object – oriented with the inheritance of private members and interfaces.

JavaScript vs TypeScript-

1. One of the main advantages of JavaScript over TypeScript is that JavaScript doesn’t require costly development tools. Developer can start with a text editor such as notepad. As JavaScript is interpreted language within web browser, so no need to buy a compiler. While, TypeScript includes programming language support expensive IDE’s.
2. JavaScript doesn’t have important features, for eg., client-side javascript doesn’t allow the read-write of files. Strongly typed object oriented compile language is TypeScript. It has set of tools available.
3. You can not use JavaScript for network application because it lacks the support and it doesn’t support multi-threading or multiprocessing.
4. TypeScript allows developers to exploit the static typing process effectively. It helps developers to find which objects are working and which are not working. Tools allow developers to locate errors and fix them properly before running the application.
5. Large applications can not develop with JavaScript. TypeScript came with a big app options to run millions of code lines.
6. Refactoring in TypeScript is safer whereas it is not possible in JavaScript.
7. Changing the browser and reloading is also faster in TypeScript as compared to JavaScript due to the use of tools.

Conclusion-

If you’re unfamiliar with TypeScript / ES6 / ES7 and just have a small web page to build, you can choose plain old JavaScript. If you’re working in a team and want to build something that has to scale and has to be maintained for a long time, you should choose TypeScript over the JavaScript.

TypeScript and its Advantages

TypeScript is a typed super-set of JavaScript that compiles to plain JavaScript. It adds optional types, classes, interfaces, and modules to JavaScript. It was developed by Microsoft and is open source.

About TypeScript

• TypeScript offers classes, modules, and interfaces to help developers build robust components.
• TypeScript types let developer define interfaces between software components and to gain insight into the behavior of existing JavaScript libraries.
• TypeScript starts from the syntax and semantics that millions of JavaScript developers know today.
• With TypeScript, developers can use existing JavaScript code, incorporate popular JavaScript libraries, and be called from other JavaScript code.
• TypeScript compiles to JavaScript code which runs on any browser, in Node.js, or in any other ES3-compatible environment.

TypeScript Features

• Type annotations and compile-time type checking
• Namespaces
• Enums (to define a set of named constants)
• Generics (classes, types, and functions that can work over a variety of types)
• Await (suspends the execution until an asynchronous function return promise is fulfilled)
• Abbreviated “arrow” syntax for anonymous functions
• Optional parameters and default parameters

Benefits of TypeScript

The benefits of TypeScript arise from its additional features and apply mostly to teams of collaborating developers who are working on large coding projects. Here are a few notable benefits:

• Declaration files. With declaration files we can add type information to your javascript libraries. This structural information will get a fantastic intelligent support in VisualStudio.
• “Standard” OOP. If anyone come from a C# or Java background they probably won’t even need a typescript tutorial. It just works. there have classes, interfaces, access modifiers, extension mechanisms, etc…
• Built-in support for modules. Typescript has a slightly confusing module system. we can split our code into several .ts files and just append them but here we can also create different modules.
• The syntax. Sometimes it’s the small things that have the biggest impact.

Primary Differences

TypeScript uses all the code found in JavaScript with other coding concepts such as classes, modules, interfaces, and types. It was created to make JavaScript development easier.

For example, TypeScript uses concepts such as types and interfaces to describe data being used. This allows developers to quickly detect errors and debug applications. Additional features include:

• Optional parameter feature.
• Rest Parameter feature.
• Generics support.
• Modules support.

Because it is a programming language, a compiler is used to convert to JavaScript so it can run on web pages.

What to Choose and When

TypeScript is becoming a tool for organizations that want to develop large coding projects. The structure of the object-oriented programming language keeps the code clean, consistent, and simple to debug.

If an experienced developer is working solo on relatively small coding projects, it may not seem necessary to work with TypeScript – however, if they want to work with a team using it, knowledge and expertise in the programming language is obviously a must. In fact, many DevOps teams look for candidates with programming skills in a variety of languages.

The relationship between the popular scripting language and its object-oriented programming language subset are important to note depending on the size of your project and the size of your team. If you need to boost productivity and write cleaner code, learning TypeScript is well worth your time.
