Getting Started with TypeScript

The core value of TypeScript is catching errors at compile time, not discovering them in production.

Basic Annotations

const name: string = 'Astro';
const count: number = 42;

Learning Tips

1. Enable strict mode in a small project first
2. Pause when reaching for any — can you narrow the type?
3. Read the error messages — they’re usually precise

Types aren’t overhead. They’re notes to your future self.
