divide array into parts of x elements code example

Example 1: javascript split array into chuncks of

function splitArrayIntoChunksOfLen(arr, len) {
  var chunks = [], i = 0, n = arr.length;
  while (i < n) {
    chunks.push(arr.slice(i, i += len));
  }
  return chunks;
}
var alphabet=['a','b','c','d','e','f'];
var alphabetPairs=splitArrayIntoChunksOfLen(alphabet,2); //split into chunks of two

Example 2: array chunk javascript

let input = [1,2,3,4,5,6,7,8];
let chunked = []
let size = 2;

Array.from({length: Math.ceil(input.length / size)}, (val, i) => {
  chunked.push(input.slice(i * size, i * size + size))
})

console.log(chunked);
