implement _.chunk()

Question

_.chunk() splits array into groups with the specific size.

Please implement your chunk(arr: any[], size: number)

chunk([1,2,3,4,5], 1)
// [[1], [2], [3], [4], [5]]

chunk([1,2,3,4,5], 2)
// [[1, 2], [3, 4], [5]]

chunk([1,2,3,4,5], 3)
// [[1, 2, 3], [4, 5]]

chunk([1,2,3,4,5], 4)
// [[1, 2, 3, 4], [5]]

chunk([1,2,3,4,5], 5)
// [[1, 2, 3, 4, 5]]

for size smaller than 1, return an empty array.

Code

/** 
 * @param {any[]} items
 * @param {number} size
 * @returns {any[][]}
 */
function chunk(items, size) {
  // your code here
}
