What does TypeScript do?: TypeScript adds optional static typing to JavaScript to enable better tooling, early error detection, and safer refactoring for large-scale codebases. It is designed to run in any browser, on any host, and within any operating system by compiling down to standard, readable JavaScript. By providing powerful features like interfaces, enums, and advanced type inference, it acts as a robust development layer that prevents common runtime errors. The compiler actively checks types during development, ensuring that complex applications remain maintainable and scalable. It allows developers to incremently adopt strict typing without sacrificing the inherent flexibility of the JavaScript ecosystem.
Who is TypeScript for?: JavaScript developers, frontend and backend engineering teams, and framework authors seeking better tooling, type safety, and maintainability for complex applications. It is suitable for professionals looking for efficiency.
How do I get started with TypeScript?: npm install -D typescript

What TypeScript does

TypeScript adds optional static typing to JavaScript to enable better tooling, early error detection, and safer refactoring for large-scale codebases. It is designed to run in any browser, on any host, and within any operating system by compiling down to standard, readable JavaScript. By providing powerful features like interfaces, enums, and advanced type inference, it acts as a robust development layer that prevents common runtime errors. The compiler actively checks types during development, ensuring that complex applications remain maintainable and scalable. It allows developers to incremently adopt strict typing without sacrificing the inherent flexibility of the JavaScript ecosystem.

JavaScript developers, frontend and backend engineering teams, and framework authors seeking better tooling, type safety, and maintainability for complex applications. It is suitable for professionals looking for efficiency.

Static Type Checking: Catch potential runtime errors at compile time by adding optional type annotations to variables and functions.
Advanced Editor Support: Enable rich autocompletion, safe refactoring, and inline documentation in IDEs like Visual Studio Code.
JavaScript Compatibility: Compile directly to clean, standards-based JavaScript that runs reliably on any modern browser or Node.js environment.
Gradual Adoption: Allow developers to incrementally add strict type checking to existing JavaScript codebases without requiring a complete rewrite.
Object-Oriented Constructs: Utilize interfaces, classes, and generic types to enforce strict architectural contracts across large engineering teams.

Where teams use it

Large-Scale Web Applications

Build complex frontend codebases where strict typing prevents regressions and facilitates collaboration among dozens of developers.

Robust Backend Development

Create resilient Node.js servers with predictable API contracts and strongly typed data models.

Library Authorship

Publish npm packages with integrated type definitions to provide immediate IntelliSense to consumers.

Safe Refactoring

Rename variables and modifying function signatures across hundreds of files with confidence that the compiler will catch all misalignments.

Getting started: npm install -D typescript

README

main branch

TypeScript

TypeScript is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the playground, and stay up to date via our blog and Twitter account.
