> Add static types and editor checks to JavaScript

TypeScript is a programming language that extends JavaScript with a type system. Developers use it to describe the shapes of objects, function inputs, and return values, helping editors identify mistakes before code runs. Type inference also supplies useful checks without requiring an annotation everywhere, while editor integration supports suggestions and code completion as a project grows.

TypeScript converts to JavaScript for use in browsers and server runtimes such as Node.js. Teams can adopt it gradually, starting with checks in existing JavaScript files and adding types over time. The compiler can be installed as a project dependency through npm and included in a build workflow. An online playground provides a quick way to try examples and inspect the JavaScript produced from TypeScript code.
