TypeScript programming language

TypeScript is an open-source programming language developed by Microsoft that builds upon JavaScript by adding static type definitions. It is a syntactical superset of JavaScript, meaning any valid JavaScript code is also valid TypeScript, and it compiles, or 'transpiles,' into plain JavaScript.

Problem solved
TypeScript addresses the limitations of JavaScript in developing large-scale, complex applications by introducing static typing, which enables better code maintainability, enhanced developer tooling, and the ability to catch many common errors at compile-time rather than runtime. This drastically improves the robustness and scalability of JavaScript projects.
