How can I split an array into chunks but have it fill each array by going one by one

Question

I\'m using this function to create chunks of an array:

function chunkArray(myArray, chunk_size) {
    let results = [];
    while (myArray.length) {

You can use the following code:

function chunkArray(myArray, chunk_size) {
    let results = new Array(chunk_size);
    for(let i = 0; i < chunk_size; i++) {
        results[i] = []
    }
    // append arrays rounding-robin into results arrays.
    myArray.forEach( (element, index) => { results[index % chunk_size].push(element) });
    return results;
}

const array = [1,2,3,4,5,6];
const result = chunkArray(array, 3)
console.log(result)
