Defining TypeScript

TypeScript is an object-oriented programming language developed and maintained by Microsoft Corporation. It is a superset of JavaScript and contains all of its elements and we can say that TypeScript is modern JavaScript with classes, optional types, interfaces and more.

TypeScript totally follows the OOPS concept and with the help of TSC (TypeScript Compiler), we can convert Typescript code (.ts file) to JavaScript (.js file)

Typescript is a superset of JavaScript.

A brief history of TypeScript

In 2010 Anders Hejlsberg (the founder of Typescript) started working on Typescript at Microsoft and in 2012 the first version of Typescript was released to public (Typescript 0.8). Although the release of Typescript was praised by many people around the world, but still due to lack of support in major IDEs, it was not majorly adopted by JavaScript community.

The first version of Typescript (Typescript 0.8) was released to public on October 2012.

The latest version of Typescript (Typescript 3.0) was released to public on July 2018 and you can
