TypeScript is a superset of JavaScript that adds optional static typing and type inference. It transpiles to JavaScript for browser compatibility while allowing for better autocomplete, refactoring, documentation and catching errors during development. TypeScript scales to large code bases and is adopted due to its open source licensing, Microsoft backing and built-in support in IDEs like WebStorm and Visual Studio Code. Tutorials provide guidance on migration and demonstrate TypeScript through code examples in a travel cloud project.

Editor's Notes
- #3: TypeScript is a superset of JavaScript which primarily provides optional static typing, classes and interfaces. One of the big benefits is to enable IDEs to provide a richer environment for spotting common errors as you type the code.
