TypeScript vs. Angular: Check the Differences

Alex Rivers

TypeScript (TS) is an object-oriented, open-source programming language and an extension of Javascript (JS). It is the superset of JavaScript. Any code written in TS is valid in JS, although the opposite might not be true in some cases. Microsoft developed it in 2012. It follows static typing and is multiparadigm, which means it is object-oriented.

Angular, on the other hand, is a framework that is used for building single-page client applications with the help of HTML and TS. It is written in TS.  It implements core and optional functionality as a set of TS libraries that you import into your applications.

Difference between TypeScript and Angular

There are few differences between the two and we shall see those few differences here.

  • TS is a programming language whereas Angular is a framework.
  • Since it is a framework, it is used for making SPAs. TS is used for developing web and mobile applications.
  • TS is a primary language for Angular application development.
  • They both are two different tools but aren’t mutually exclusive.
  • An Angular workspace contains several TS configuration files.

Is TypeScript Needed For Angular?

Yes, it is. In fact, Angular is written in TS. The TS environment is very important to Angular developers. Also, Angular and TS have helped in enhancing JavaScript.

Is TypeScript part of Angular?

TS is a primary language for Angular application development. It is a superset of JavaScript with design-time support for type safety and tooling. Browsers find it difficult to execute TS directly. So, they first get transpiled into JS and then execution happens.

If someone wants to learn Angular, they should know TS, especially for Angular 2. TS is the main programming language for it. Thus, TS is very important for Angular 2.

Why is TypeScript used in Angular instead of JavaScript?

This is so because TypeScript is the primary language for development in Angular. The code in TypeScript is easier to refactor and this is what makes it suitable for Angular. However, some developers claim that Angular can be used with ES5 and, so, you can use JavaScript. TypeScript is the superset of JavaScript and can be interchangeably used. But, that can be a hassle and since Angular was born out of TypeScript, it is best to use TS instead of JS for development. That way things will be easy and hassle-free.


It is difficult to find differences between the two but certainly, there are a few of them that have been pointed out. Both the tools are important for development. Angular and TS compliment each other.

Happy Coding!
