What is TypeScript and why would you use it?

TypeScript is a statically typed superset of JavaScript developed by Microsoft. • Static Typing: Provides compile-time type checking • Better IDE Support: Enhanced autocomplete, refactoring, and navigation • Early Error Detection: Catches errors during development • Improved Code Quality: Makes code more maintainable and readable • Modern JavaScript Features: Supports latest ECMAScript features // Example: Type safety function greet(name: string): string { return 'Hello, ' + name + '!'; } greet(123); // Error: Argument of type 'number' is not assignable to parameter of type 'string' Benefits: • Reduces runtime errors • Improves team collaboration • Better documentation through types • Easier refactoring of large codebases.
