Splits an array into subarrays of a specified length.

arraySplitter.js

function subArray(array, length) {
  // get an array
  // for each over the array
  // if the index is length spots in
  // the numbers it traversed should be kept in an
  // new array
  let storage = [];
  let i = 0;
  //
  while (storage.length < (array.length / length)) {
    // takes length amount of numbers from the original and push them into
    // smaller array which is then pushed into storage
    let subArr = array.slice(i, i + length);
    storage.push(subArr);
    console.log(storage);
    i += length;
  }
  return storage;
}

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