What is Type Script ?

TypeScript is a free and open-source programming language developed and maintained by Microsoft. It is a strict syntactical super set of JavaScript.

TypeScript may be used to develop JavaScript applications for client-side or server-side (Node.js) execution.

TypeScript is designed for development of large applications and compiles to JavaScript. As TypeScript is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs.

The TypeScript compiler is itself written in TypeScript and compiled to JavaScript.

TypeScript lets you write JavaScript the way you really want to.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

TypeScript is pure object oriented with classes, interfaces and statically typed like C# or Java.

The popular JavaScript framework Angular 2.0 is written in TypeScript.

Mastering TypeScript can help programmers to write object-oriented programs and have them compiled to JavaScript, both on server side and client side.
