About Typescript Handbook
The TypeScript Handbook is the official documentation repository for the TypeScript programming language, hosted on GitHub by Microsoft. It provides comprehensive, in-depth coverage of TypeScript's type system, syntax, and advanced features through a series of well-organized Markdown documents. Topics include basic and advanced types, classes, functions, generics, interfaces, modules, decorators, utility types, and more. The repository is archived and read-only as of October 2022, but continues to serve as a definitive reference for developers learning or working with TypeScript.
