Typescript vs. Javascript

A lot has been said, in general, of the powerfully built features of Javascript (JS), and some of our previous blogs too dealt with how it can easily enhance your website’s HTML pages. While Typescript is more a superset of JS, or let’s put it like Typescript is sort of Javascript with some added features. Let’s have a look at Typescript vs Javascript head-on in this blog: 


  1. Typescript: A powerful type of object oriented compile language.
  2. Javascript: A high-level, interpreted programming language.

Designed & developed by:

  1. Typescript: Anders Hejlsberg at Microsoft
  2. Javascript: Brendan Eich at Netscape Communications Corpora, Mozilla Foundation, ECMA International

Light/Heavy Weight:

  1. Typescript: A highly lightweight interpreted coding language
  2. Javascript: Not as lightweight as Typescript; designed for the development of huge applications and trans compile to JS.

Server Side/ Client Side:

  1. Typescript: Particularly employed in client side.
  2. Javascript: Both client as well as server side.

File Extension

  1. Typescript: .ts, .tsx
  2. Javascript: .js


  1. Typescript: Syntax refers to the set of rules and processes for coding or writing programs. Every programming language specifies its own bit of syntax. A type script program comprises Functions, Modules, Statement & Expressions, Variables and Comments. 
  2. JavaScript: All statements are written inside of Script tag. It requests the browser program to interpret and execute all the text that comes between these tags like a script. <script>//javascript code</script>

Benefits of Typescript:

      1. Static Typing

      2. Better fit for complex coding projects

      3. Fit for collaboration

      4. Lesser chances for messier coding as it offers improved collaboration. The frequency of errors is reduced and it makes handling easy. Therefore, Type safety comes with a feature that helps coders determine errors when you’re coding. This means cleaner code with efficient debugging.

Benefits of Javascript:

      1. It has a large pool of developer communities, being highly popular.  

      2. Native browsers supported. In the case of Typescript, it will first compile and change to JS which is an extra step.  

      3. With raw JS, it is tough to maintain the lines of code error-free, especially when the size becomes heavier than Typescript.

      4. Increased flexibility.

Why choose?

  1. Typescript: As Typescript is an object-oriented language, it makes the code more reusable, simple, clean and consistent .So it is recommended to employ Typescript for building huge projects.
  2. Javascript:  JS is perfect for comparatively smaller coding projects.

On a final note...

All said and done, Typescript as well JavaScript is built with its own limitations and features.  JS is a lightweighted and dynamic coding language particularly for improving HTML web pages. However, it is not a full-fledged coding language. As an interpreted programming language, JS comes inside a web browser’s context.

Typescript is compiled to JS which can be employed for any JS code; therefore, Typescript comes with more benefits which makes it more commonplace and popular. We are also seeing more improvements with each release and amazing typescript features added with subsequent releases.
