Divide Array into Chunks [Edabit]

Edabit

Write a function that divides an array into chunks of size n, where n is the length of each chunk.

Examples

chunkify([2, 3, 4, 5], 2) ➞ [[2, 3], [4, 5]]

chunkify([2, 3, 4, 5, 6], 2) ➞ [[2, 3], [4, 5], [6]]

chunkify([2, 3, 4, 5, 6, 7], 3) ➞ [[2, 3, 4], [5, 6, 7]]

chunkify([2, 3, 4, 5, 6, 7], 1) ➞ [[2], [3], [4], [5], [6], [7]]

chunkify([2, 3, 4, 5, 6, 7], 7) ➞ [[2, 3, 4, 5, 6, 7]]

Notes

• It’s O.K. if the last chunk is not completely filled (see example #2).
• Integers will always be single-digit.

Solution:

function chunkify(arr, size) {
  let sol = [];
  while (arr.length) {
    let temp = [];
    let len = size;
    while (len--) {
      if (!arr.length) break;
      temp.push(arr.shift());
    }
    sol.push(temp);
  }
  return sol;
}

function chunkify(arr, size) {
  let sol = [];
  while (arr.length) {
    sol.push(arr.splice(0,size));
  }
  return sol;
}
