What is TypeScript?

Technical terms explained. Learn more about TypeScript

TypeScript is a superset of JavaScript that compiles to JavaScript. Which means that any valid JavaScript will work in TypeScript.

TypeScript compiles to clean, simple JavaScript code which runs on any browser, in Node.js, or in any JavaScript engine that supports ECMAScript 3 (or newer).

TypeScript offers support for the latest and evolving JavaScript features, including those from ECMAScript 2015 and future proposals, like async functions and decorators, to help build robust components.

These features are available at development time for high-confidence app development, but are compiled into simple JavaScript that targets ECMAScript 3 (or newer) environments.

Typescript is the default language in Angular applications.
