Olawale/FreeCodeCamp Algorithm: Chunk Array in Groups

chunk_array.js

function chunkArrayInGroups(arr, size) {
  // A variable to keep the chunked arrays
  var holder = [];
  // While the length of the arr is greater than 0
  while(arr.length > 0){
      // Splice from index 0 to size and push the spliced item into the holder array
      // arr.splice() mutates the arr
      holder.push(arr.splice(0, size));
} //  End of while loop
// Return the holder arr
return holder;
}
chunkArrayInGroups(["a", "b", "c", "d" , "e"], 2);
