Tell us what’s happening:

Your code so far

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

chunkArrayInGroups(["a", "b", "c", "d","e","f"], 2);

slice(i,size) will extract elements from index i to size(exclusive) unlike in splice where size number of elements are extracted from the index i .so basically the statement inside the for loop is doing this:

i=0 slice(0,2) myarr={["a","b"]}
i=1 slice(2,2) myarr={["a","b"],[]} //this is because you are trying to slice elemnt s
from index 2 to 2 
i=1 slice(4,2) myarr={["a","b"],[],[]}//again trying to slice elemnt from index 4 to index 2

what you could do is change myarr.push(arr.slice(i,size+i));
so that it extracts elements from i to i+size

i=0 slice(0,2) myarr={["a","b"]}
i=2 slice(2,4) myarr={["a", "b"], ["c", "d"]}
i=4 slice(4,6) myarr={["a", "b"], ["c", "d"],["e","f"]}

this would work as expected
