@ -5,7 +5,7 @@ Initializes an array containing the numbers in the specified range where `start`
Use `Array(Math.ceil((end+1-start)/step)` to create an array of the desired length(the amounts of elements is equal to `(end-start)/step` or `(end+1-start)/step` for inclusive end), `Array.map()` to fill with the desired values in a range.
You can omit `start` to use a default value of `0`.
You can omit `step` to use a default value of `1`.
```js
const initializeArrayWithRange = (end, start = 0, step = 1) =>
Array.from({ length: Math.ceil((end + 1 - start) / step) }).map((v, i) => i * step + start);
