Parameters

array

Array of subarrays of $array of length $countItemsInArray. Last element can be shorter if $countItemsInArray doesn't divide the length of $array evenly.

Examples

{
  a: split_array(`[1, 2, 3, 4]`, `1`),
  b: split_array(`[1, 2, 3, 4]`, `3`),
  c: split_array(`[1, 2, 3, 4]`, `5`),
  d: split_array(`[1, 2, 3, 4]`, `-1`),     // Error
  e: split_array(`[1, 2, 3, 4]`, `2.0`),
  f: split_array(`[1, 2, 3, 4]`, `true`),
  g: split_array(`[1, 2, 3, 4]`, `null`)    // Error
