### chunk
|
|
|
|
Chunks an array into smaller arrays of a specified size.
|
|
|
|
Use `Array.from()` to create a new array, that fits the number of chunks that will be produced.
|
|
Use `Array.slice()` to map each element of the new array to a chunk the length of `size`.
|
|
If the original array can't be split evenly, the final chunk will contain the remaining elements.
|
|
|
|
```js
|
|
const chunk = (arr, size) =>
|
|
Array.from({length: Math.ceil(arr.length / size)}, (v, i) => arr.slice(i * size, i * size + size));
|
|
// chunk([1,2,3,4,5], 2) -> [[1,2],[3,4],[5]]
|
|
```
