Chunky Monkey logic explanation problem

JavaScript
1

My code is correct for all the problems, but I need help on the logic of this code why it is correct. For this code, I would slice for the first time will be slice(i=0,size), and for the next slice(i+size, size +1) which will give the newArray value when push is [[0,1,2],[3,4,5]].But, how come the array [6] still push inside the newArray? Appreciate you could help me on this logic?

Thank you.

Your code so far

function chunkArrayInGroups(arr, size) {
  // Break it up.
  var array = [];
  var newArray = [];
   
  for (i=0;i<arr.length;i+= size){
    newArray.push(arr.slice(i, size+i));
  }
  
  return newArray;
}

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