TypeScript provides static typing, better tooling with autocompletion, early error detection, improved code documentation, and better refactoring support.

2

What is the relationship between TypeScript and JavaScript?

TypeScript is a superset of JavaScript, meaning all valid JavaScript code is also valid TypeScript code. TypeScript compiles down to JavaScript for execution.

What are TypeScript interfaces and how are they used?

Interfaces define contracts in code, specifying the structure that objects must follow. They help with type-checking but don't generate any JavaScript code at runtime.
