Write a function that splits an array (first argument) into groups the length of size (second argument) and returns them as a multidimensional array

Question

I am working through a javascript problem that asks me to:

Write a function that splits an array (first argument) into groups the length of size (second argument) an

Answer 1

Another version:

function chunk(arr, size) {
    var result = [];
    while (arr.length > size) {
        result.push(arr.splice(0, size))
    }
    if (arr.length)
        result.push(arr);

    return result;
}

Answer 2

function chunk(arr, size) {

  var arr1=[];
  var j=0,temp=size;
  var len = arr.length/size;
  for (var i=0; i<len; i++){
    arr1.push(arr.slice(j,size));
    j+=temp;
    size+=temp;
  }
  return arr1;
}

chunk([0, 1, 2, 3, 4, 5], 2);

Answer 3

This is my solution:

function chunkArrayInGroups(arr, size) {
  var acum=[];
  for(i=0;i<arr.length;i=i+size)
  {
    var vec=arr.slice(i,size+i);
    acum.push(vec);
  }

  return acum;
}
