TypeScript

Adds type annotations to JavaScript code to catch errors early during development.

Provides enhanced tooling such as auto-complete, inline documentation, and error checking in supported editors.

Allows incremental typing of existing JavaScript projects without full rewrites.

Automatically infers types to reduce the need for explicit annotations while maintaining type safety.

Compiles to plain JavaScript that runs on browsers, Node.js, Deno, Bun, and other JavaScript environments.

Supports interfaces, enums, generics, union types, intersection types, and more advanced type constructs.

Enables describing existing JavaScript libraries with type definitions for safer integration.

Includes extensive handbook, tutorials, and references for learning and using TypeScript effectively.
