### Fill array
Use `Array.map()` to map values between `start` (inclusive) and `end` (exclusive) to `value`.
Omit `start` to start at the first element and/or `end` to finish at the last.
```js
const fillArray = (arr, value, start = 0, end = arr.length) =>
arr.map((v, i) => i >= start && i < end ? value : v);
// fillArray([1,2,3,4],'8',1,3) -> [1,'8','8',4]
