🌀 extension： [Iterator](/web/js/iteration/iterator/iterator.md) - extend built-in [iterable iterator](/web/js/iteration/iterator/iterable.md)s.

```javascript
// ⭐️ infinite sequence: 0, 1, 2 ... 
function* integers() {
    let i = 0;
    while (true) { yield i++ }
}
```

💈範例：

```javascript
// ⭐️ iterable destructuring
const [a, b, c] = integers();
console.log(a, b, c);            // 0, 1, 2
```
