About microsoft/typescript

TypeScript is a programming language built by Microsoft that extends JavaScript with optional static typing. It compiles down to clean, readable JavaScript that runs in any browser, on any host, and on any operating system. The language is designed to support large-scale application development, providing tools and type checking that help developers catch errors early and write more maintainable code.

The project is one of the most widely-used language tools in web development, with a playground available for testing and regular updates shared through an official blog and social media. TypeScript can be installed via npm for stable versions or nightly builds, and extensive documentation is available including quick-start guides and a comprehensive programming handbook.

The repository currently limits code contributions to a narrow set of critical fixes including crashes, security issues, and serious regressions, with most other bug fixes directed to the typescript-go repository. The project maintains an active community across multiple platforms including Discord, Stack Overflow, and Twitter, and welcomes participation through bug reporting, code review, and discussion among TypeScript developers and users worldwide.
