Javascript is not a strong object-oriented programming based language. Nowadays, Object-oriented programming based languages are very popular because they help developers to develop large programmes with less coding. Javascript lacks OOP most features and to overcome this problem an upgraded version of this language was introduced in the market called Typescript.

Typescript is the same as javascript but it has more features like static typing, sub-interfaces, ES6 support and more. In other words, we can say that it is the extended version of javascript. In this article, we have provided comprehensive information by comparing both languages.
