Add optional types to large-scale JavaScript applications
TypeScript lets you add type information to JavaScript code regardless of the browser, server, or operating system. As a superset of JavaScript, it makes code easier to read and compiles it to standard-based JavaScript. This helps reduce errors in large application development and enables the use of tools.
Installation
Install the latest stable version with the npm install -D typescript command. Use npm install -D typescript@next if you want the nightly build that updates daily. This project is written in the Go language.
Documentation and Learning Resources
A guide to learning TypeScript in five minutes, a programming handbook, and a homepage are provided. These materials allow you to quickly learn the basic concepts and usage of the language.
Community and Contribution
You can interact with other users and developers on StackOverflow, Discord, and the #typescript channel on Twitter. You can contribute to the project in various ways, such as reporting bugs, verifying fixes, reviewing source code, and fixing bugs. This project follows the Microsoft Open Source Code of Conduct.
Roadmap and Direction
Refer to the official roadmap for details on planned features and future direction. The README does not specify concrete version-by-version changes or the latest announcements.
Suitable Situations
This repository is recommended if you want to use a type checker and tools when developing large-scale JavaScript applications. It compiles to standard-based JavaScript that runs on all browsers, hosts, and operating systems, so you do not need to worry about compatibility issues. However, because TypeScript is a superset of JavaScript, it can be used alongside existing JavaScript code. Before installing, you must ensure that your project's Node.js environment and npm version are compatible with the latest stable version.
