👉 compare： [ClosedRange](/web/js/iteration/iterable/custom/closedrange.md) (the hard way), [\*list()](/web/js/iteration/generator/examples/list.md)

```javascript
// ⭐️ (closed) range of integers
function* closedRange(start, end) {
    for (let i = start; i <= end; i++) { yield i }
}
```

💈範例：

```javascript

for (const i of closedRange(1, 3)) console.log(i);  // 1 2 3
[...closedRange(-2, 2)],                            // [ -2, -1, 0, 1, 2 ]
```
