Chunky Monkey Loop Help

Tell us what’s happening:
Alright…I am stuck. When I console.log my code, it appears that test 3,4,5,6 (in the list of tests) are not looping through all the way. The other tests pass. I have worked out the code manually on paper and do not see why this is happening.

For example, the second to last test passes [0, 1, 2, 3, 4, 5, 6, 7, 8] as the first argument, and 4 as the second argument. It should return [0, 1, 2, 3], [4, 5, 6, 7], [8]. But I am getting [0,1,2,3,],[4,5,6,7] with just an empty array at the end.

Any ideas as to what is happening is appreciated!

Thanks,
David

Your code so far

function chunkArrayInGroups(arr, size) {
  
  var newArray = [];
  var startCut = 0;
  var endCut = size;
                
  
  for (i = 0; i < arr.length/size; i++) {
    newArray.push(arr.slice(startCut, endCut));
     startCut = startCut + size;
     endCut = size + size;
      } 
  

console.log(newArray);
}

chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6, 7, 8], 2);

i < arr.length/size
How might this be a problem? What does it do?

My intention with that was to have it iterate through the loop he correct number of times based on the output I needed. Is this where my problem is? My thought process was this:

1st Test: arr.length is 4, size argument is 2 - the desired output has 2 sub arrays.
2nd Test: arr.length is 6, size argument is 3, desired output has 2 sub arrays.
