About TypeScript

TypeScript is an open-source programming language developed by Microsoft. It's a superset of JavaScript, meaning that it builds on top of JavaScript by adding static typing and other features to help developers write more robust and scalable code.

TypeScript compiles down to plain JavaScript, allowing it to run on any browser or JavaScript engine. It's particularly popular for large-scale JavaScript applications, as it helps catch errors early in the development process and provides better tooling support for complex projects.
