DESCRIPTION:
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()
*/

const chunkyMonkey = (values, size) => {
    const result = []
    
        for(i=0; i < values.length; i += size) {
            result.push(values.slice(i, i + size))
        }
        return result
}
