Write a function that splits an array (first argument) into groups the length of size (second argument) and returns them as a two-dimensional array.

Example

• chunkyMonkey(["a", "b", "c", "d"], 2) should return [["a", "b"], ["c", "d"]].
• chunkyMonkey([0, 1, 2, 3, 4, 5], 4) should return [[0, 1, 2, 3], [4, 5]].

Hints

• slice()
