Problem statement

\n

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

\n

Solution

\n
const arrayChunk = (array, size) => {\n  const chunkedArray = []\n  let index = 0\n\n  while (index < array.length) {\n    chunkedArray.push(array.slice(index, index + size))\n    index += size\n  }\n\n  return chunkedArray\n}\n\nconsole.log(arrayChunk([1, 2, 3, 4, 5, 6], 2))\n// [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]\n\nconsole.log(arrayChunk([1, 2, 3, 4, 5, 6], 4))\n// [ [ 1, 2, 3, 4 ], [ 5, 6 ] ]

JavaScript while loop

\n
while (condition)\n      statement
\n

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

\n
let n = 5;\nconst nums = [];\n\nwhile (n < 10) {\n  nums.push("a");\n  n++;\n}\n\nconsole.log(nums);\n\n``\n\n###### Find out more about Array.slice() in my blog post [here](https://hemanta.io/javascript-subarrays-with-slice-and-splice/)
