Function columnify

Takes an array and returns an array of arrays with a length of columnsNumber.

  • If columns number is greater than the length of the input array, the resulting arrays will be empty.
  • If columnsNumber is less than 1, it will be set to 1.
  • The resulting arrays contain the elements of the original array, distributed in a columnar fashion.

Example

const a = [1, 2, 3, 4, 5, 6];
const b = columnify(2)(a);
console.log(b); // [[1, 3, 5], [2, 4, 6]]
