Finds all arrays of consecutive elements.
|
|
|
|
- Use `Array.prototype.slice()` to create an array with `n - 1` elements removed from the start.
|
|
- Use `Array.prototype.map()` and `Array.prototype.slice()` to map each element to an array of `n` consecutive elements.
|
|
|
|
```js
|
|
const findConsecutive = (arr, n) =>
|
|
arr.slice(n - 1).map((v, i) => arr.slice(i, i + n));
|
|
```
|
|
|
|
```js
|
|
findConsecutive([1, 2, 3, 4, 5], 2);
|
|
// [[1, 2], [2, 3], [3, 4], [4, 5]]
|
|
```
