What is TypeScript and why does Angular use it?

beginner

Re-explain

TypeScript is a superset of JavaScript that adds static typing and other features. Angular uses TypeScript because:

Type Safety: Catches errors at compile time rather than runtime
Better IDE Support: Enhanced autocomplete, refactoring, and navigation
Object-Oriented Programming: Supports classes, interfaces, and inheritance
Modern JavaScript Features: Supports ES6+ features while maintaining backward compatibility
Better Maintainability: Makes large codebases easier to manage
Enhanced Debugging: Better error messages and debugging experience
