What is TypeScript?
Definition
TypeScript is a typed superset of JavaScript developed by Microsoft. It adds static type checking, interfaces, enums, and generics. TypeScript code compiles to plain JavaScript that runs in any browser or Node.js environment.
Why It Matters
TypeScript catches type-related bugs at compile time rather than runtime, improving code quality and developer productivity in large codebases. It is the standard for Angular, widely adopted in React/Vue projects, and used by most enterprise JavaScript applications.
