Problem statement

Given an array and chunk size, divide an array into as many subarrays as possible where each subarray is of the length chunk size.

Solution

const arrayChunk = (array, size) => {
  const chunkedArray = []
  let index = 0

  while (index < array.length) {
    chunkedArray.push(array.slice(index, index + size))
    index += size
  }

  return chunkedArray
}

console.log(arrayChunk([1, 2, 3, 4, 5, 6], 2))
// [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]

console.log(arrayChunk([1, 2, 3, 4, 5, 6], 4))
// [ [ 1, 2, 3, 4 ], [ 5, 6 ] ]

JavaScript while loop

while (condition)
      statement

The while statement creates a loop that executes a specified statement as long as the test condition evaluates to true.

let n = 5;
const nums = [];

while (n < 10) {
  nums.push("a");
  n++;
}

console.log(nums);
