TypeScript is a superset of JavaScript that adds optional static typing and enables tools for catching errors. It aims to solve issues like JavaScript being weird and lacking type safety by adding types and compile-time checks without sacrificing JavaScript's runtime behavior. TypeScript code compiles to plain JavaScript code, allowing it to run anywhere JavaScript runs.
