[Javascript] Chunk array

Array.from() is a great way to chunk up arrays because of the secondary argument being a map function.

const hugeArray = Array.from({length: 76}, (_, i) => i)

function chunkify(array, chunkSize = 10) {
    const chunks = Array.from(
     {length: Math.ceil(array.length / chunkSize)},
     (_, i) => {
       const start = chunkSize * i;
       return array.slice(start, start + chunkSize)
     }
    )
    return chunks
}

console.log(chunkify(hugeArray))
