If you are an enthusiastic software developer or student then learning the programming language is very important. But ensure that you are going to learn the right language that is on the trend. According to PYPN, Javascript is the third most popular programming language in the world. It is used for developing creative web pages along with HTML, CSS.Initially, it was developed as a client-side scripting language and after some time, developers have realized that it can be used as a server-side scripting language also.

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.

A new version of Javascript

Typescript is an open source project that offers many features of object-oriented programming like classes, modules, interfaces and more. However, Javascript focuses on client-side scripting.
