Script Preparation code:

var test = Array.from({
    length: 100000
}, () => Math.random())
function createGroupedArray(arr, chunkSize) {
    const groups = [];
    let i = 0;
    while (i < arr.length) {
        groups.push(arr.slice(i, i += chunkSize));
    }
    return groups;
};

function array_to_chunks(data, size){
   let chunks = []
   let d = data.slice()
   while (d.length >= size) chunks.push(d.splice(0, size))
   return chunks
}

const chunk = (arr, chunkSize = 1, cache = []) => {
  const tmp = [...arr]
  if (chunkSize <= 0) return cache
  while (tmp.length) cache.push(tmp.splice(0, chunkSize))
  return cache
}
