Iterate through various lists according to their respective sizes

I am working on a project that involves 6 lists of objects with varying sizes.

My task is to iterate through all the lists in a specific order, starting from the smallest list to the largest one.

var list_1 = [...]    // length 24
var list_2 = [...]    // length 4
var list_3 = [...]    // length 3
var list_4 = [...]    // length 4
var list_5 = [...]    // length 11
var list_6 = [...]    // length 2

// I need a code snippet here to loop through each list in ascending order
list_6.forEach(...)   // length 2
list_3.forEach(...)   // length 3
list_2.forEach(...)   // length 4
list_4.forEach(...)   // length 4
list_5.forEach(...)   // length 11
list_1.forEach(...)   // length 24

If anyone has a straightforward solution for this issue, I would greatly appreciate it. Thank you!

Answer №1

To efficiently combine lists, you can store them in an array, sort the array, and then iterate through each list using a loop.

[list1, list2, ...]
    .sort((a, b) => a.length - b.length)
    .forEach(array => array.forEach(...))

Answer №2

Combine the lists and arrange them in ascending order.

const listOne = [5, 7, 1, 3],
  listTwo = [10, 8],
  listThree = [6, 2, 4];

let listOfListsCombined = [listOne, listTwo, listThree].sort((a, b) => a.length - b.length);

console.log(listOfListsCombined);
listOfListsCombined.forEach(combinedList => {
  combinedList.forEach(item => {
    console.log(item);
  });
});
