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