Typescript and javascript both are the programming language that is used by clients at the front end for processing the server request and rendering data on UI. Although both typescript and javascript are scripting languages, typescript supports more additional features than javascript. To know further about Typescript, and Javascript, their respective features, how are they different from each other, and which one’s better. Read the article till the end.

What is Typescript?
Typescript can be considered as the superset of javascript. It is a modern age javascript development language. A typescript is an object-oriented and open-source programming language that is maintained by Microsoft. Typescript appends static types to JavaScript. And is statically compiled to write clear and simpler javascript codes. It completes javascript and adds a declarative structure to it. Typescript is used to develop extensive applications.
Typescript uses transpiler, that is, a source to source compiler that converts one language into another. It also supports the files with C++ header files. This permits the other programs to exercise the values that are well-defined in files.
Typescript Characteristics/ Features:
Below is a list of characteristics/ features of typescript.
- TypeScript supports javascript libraries & API Documentation
- It is considered a superset of JavaScript
- It is an exceptional typed scripting language
- The typescript code can also be converted into simple JavaScript Code
- It has better code structuring and follows object-oriented programming techniques
- It grants better development time tool
- It can extend the standard of language beyond the decorators.
- It is compiled to create clear and readable JavaScript.
- It extends the syntax of javascript so that any JavaScript programs will work with TypeScript without any changes.
- When the script is compiled it produces JavaScript to ensure compatibility.
- The command-line TypeScript compiler is able to install a Node.js package.
- TypeScript is supported by most of the popular developer IDEs including Visual Studio, Visual Studio Code, Sublime Text, Atom, Eclipse, Emacs, WebStorm, and Vim.
What is JavaScript?
Javascript is a scripting language that allows users to create interactive web pages. It works at the front end and keeps up with rules of client-side programming hence it works without any need for resources from the server. It is one of the most popular programming languages for web development. Different from other languages that use compilers to translate the code, JS uses an interpreter to convert the code into machine language.
JavaScript Characteristics/ Feature:
Below is a list of characteristics/ features of typescript.
- It is an Open-source project with Microsoft’s patronage
- It is a tool designed especially for small scripts
- It supports classes, interfaces & modules.
- A compiled JavaScript can be run in any browser
- It allows cross-compilation
- It is extendable to write larger application programs.
- It acts as a support for classes, interfaces, and modules
- It is a high-level scripting programming language.
- It is a multi-paradigm programming language that supports various programming styles like event-driven, functional, and imperative.
- Structured programming syntax of javascript is similar to C language and also supports common statements that include if statement, while loops, switch statements and do while loop.
- While JavaScript prominently runs on the front end i.e. in the user’s browser, it also can be run on the back end and there are also many JS based libraries and frameworks that are available currently.
Typescript v/s Javascript: How are they different?
Typescript:
- It is object-oriented programming and has a compiler.
- It supports static typing and a variable must be declared before use.
- It supports interfaces.
- Not only interfaces it also supports optional parameters.
- It supports REST parameters and also supports generics.
- It was designed by Microsoft and released in 2012.
Javascript:
- Javascript is a scripting language and uses an interpreter.
- It supports dynamic typing, however, it just stores the data.
- It doesn’t support an interface.
- It doesn’t support optional parameters.
- It also doesn’t support REST parameters and generics either.
- It was designed by Brendan Eich and released in 1995.
Why do we need Typescript if we have Javascript?
Well, we basically do not need typescript but it adds a lot of value to the work. It adds something that an ECMAScript does not have i.e. type safety. Typescript simplifies the javascript codes, making it much more easier to read and find errors. Typescript turns out to be a really helpful and highly productive tool for Javascript IDEs and other practices. The reason it exists is because it has some features that aren’t present natively in javascript and it cannot implement it on its own.
Which one is Better: Typescript Or JavaScript
It can be pretty tough to say as javascript is used for ages and is really popular at what it does and typescript came up with some weak points of javascript that it enhances and makes it easier to work with javascript.
