how to split array by the length of elements in javascript 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 = [1,2,3,4,5,6,7,8,9];
let chunked = []
let size = 2;

for (let i = 0;  i < input.length; i += size) {
  chunked.push(input.slice(i, i + size))
}
console.log(chunked)

Example 3: array chunk javascript

//#Source https://bit.ly/2neWfJ2 
const chunk = (arr, size) =>
  Array.from({ length: Math.ceil(arr.length / size) }, (v, i) =>
    arr.slice(i * size, i * size + size)
  );
console.log(chunk([1, 2, 3, 4, 5], 2));

Example 4: javascript how to split array into subarrays javascript

// Example array.
let randomArray = [3, 5, 1, 5, 7,];
// Create an empty array.
let arrayOfArrays = [];

function splitArray( array ) {
    while (array.length > 0) {
        let arrayElement = array.splice(0,1);
        arrayOfArrays.push(arrayElement);
    }
    return arrayOfArrays;
}

// Call the function while passing in an array of your choice.
splitArray(randomArray)
// => [ [ 3 ], [ 5 ], [ 1 ], [ 5 ], [ 7 ] ]
