Script Preparation code:

const chunkSize = 100
const arr = [];
for (var i = 0; i < 10000; i++) {
  list.push(i);
}

Tests:

slice
const res = [] for (let i = 0; i < arr.length; i += chunkSize) { res.push(arr.slice(i, i + chunkSize)) }
splice
const res = [] while (arr.length > 0) { const chunk = arr.splice(0, chunkSize) res.push(chunk) }
