Tests:

native slice
const chunkSize = 80; const chunks = []; for (let i = 0; i <= test.length; i += chunkSize) { chunks.push(test.slice(i, i + chunkSize)); }
native reduce
const chunkSize = 80; test.reduce((accu, element, idx) => { if (idx % chunkSize === 0) { accu.push([]); } const chunk = accu[accu.length - 1]; chunk.push(element); return accu; }, []);
lodash chunk
_.chunk(test,80)
