TypeScript is a statically typed superset of JavaScript that compiles to plain JavaScript. By adding type annotations, interfaces, and other powerful features, TypeScript improves the scalability, maintainability, and readability of JavaScript code. It's increasingly popular in large-scale web applications, especially for teams working on JavaScript projects.

Whether you're a JavaScript developer looking to switch to TypeScript or you're new to both, this page provides the essential resources to get you started with TypeScript and explore its advanced features for creating high-performance, type-safe applications.
