TypeScript (TS) is an open-source programming language developed by Microsoft, built on top of JavaScript but enhanced with static typing and modern features. With TypeScript, developers can write more maintainable, scalable, and error-resistant code—ideal for large-scale applications.
💡 TypeScript = JavaScript + Static Types + Powerful Tools for Large Projects.
