JavaScript Generators

What are Generators?

Generators are functions that can pause and resume. They yield values one at a time.

```javascript function* numberGenerator() { yield 1; yield 2; yield 3; }

const gen = numberGenerator(); gen.next(); // { value: 1, done: false } gen.next(); // { value: 2, done: false } gen.next(); // { value: 3, done: true } ```

Key Takeaway

Generators yield values lazily. Use for infinite sequences or memory-efficient iteration. Advanced feature for specific use cases.
