 ### Chunk Array
 
-Creates an array of elements split into groups the length of size. 
-If array can't be split evenly, the final chunk will be the remaining elements.
+Use `Array.apply()` 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`.
+If the original array can't be split evenly, the final chunk will contain the remaining elements.
 
 ```js
 const chunk = (arr, size) => 
-  Array
-    .apply(null, {length: Math.ceil(arr.length/size) })
-    .map((value, index) => arr.slice(index*size, index*size+size) )
+  Array.apply(null, {length: Math.ceil(arr.length/size)}).map((v, i) => arr.slice(i*size, i*size+size));
 
 // const myArray = [2, 2, 2, 2, 2, 2, 3, 2, 3, 2, 3, 2, 2];
 // chunk(myArray, 3) -> [ [ 2, 2, 2 ], [ 2, 2, 2 ], [ 3, 2, 3 ], [ 2, 3, 2 ], [ 2 ] ]
