* Creates an array of elements split into groups the length of `size`.

* @category Array
* @param {Array} array The array to process.
* @param {number} [size=1] The length of each chunk
* @returns {Array} Returns the new array of chunks.
* @example
*
* chunk(['a', 'b', 'c', 'd'], 2)
* // => [['a', 'b'], ['c', 'd']]
*
* chunk(['a', 'b', 'c', 'd'], 3)
* // => [['a', 'b', 'c'], ['d']]
