Splitting array into list of subarrays in javascript

split-into-subarrays.js

/*
* Splits array into subarrays.
* count parameter indicates that how many item per subarray contains.
* Example usage: splitIntoSubArray([1,2,3,4,5], 2) -> [[1, 2], [3, 4], [5]]
*/
function splitIntoSubArray(arr, count) {
  var newArray = [];
  while (arr.length > 0) {
    newArray.push(arr.splice(0, count)); 
  }
  return newArray;
}

Thank you!

Nice, but splice mutate array

Hi @Andrew-Dyachenko,

Yes it has side effect. You may want to see different approaches on this problem: https://gist.github.com/webinista/11240585

Hi @Andrew-Dyachenko,
what about this -

        sp_array = [1,2,3,4,5,6,7,8,9,10]
        let pivot = _.ceil(sp_array.length / 4);
        array_chunk = _.chunk(sp_array, pivot);

Thanks, but it seems that it needs underscore.js dependency.
