TypeScript
TypeScript is a typed superset of JavaScript that combines the flexibility and general syntax of JavaScript with a type checker and syntax. It’s one of the fastest-growing and most popular languages on the web today.
Code written in TypeScript compiles to regular JavaScript. Anything you write in TypeScript can be run wherever it could be in JavaScript: web browsers, Node servers, and more.
