siddharthray / chunkify.js
Created October 21, 2019 20:49 — forked from wesbos/chunkify.js
// this is a big array of 76 items I need to split into groups of 10
const hugeArray = Array.from({ length: 76 }, (_, i) => i);
function chunkify(array, chunkSize = 10) {
// make a new array
const chunks = Array.from(
// give it however many slots are needed - in our case 8
// 1-7 with 10 items, and 8th slot will have 6
{ length: Math.ceil(array.length / chunkSize) },
// this is a map function that will fill up our slots
