Approach Using Array.from() Method
One way of generating the array is to use the in-built Array.from() Method which will create an array out of the elements of the set. To know more about the method, follow this link.
Syntax:
# myset is the set under consideration for this article
myArray = Array.from(myset)
myArray.sort()
Example: In this example, we are using Array.from() Method
// Initialize a Set object
// using Set() constructor
let myset = new Set()
// Insert new elements in the
// set using add() method
myset.add(3);
myset.add(2);
myset.add(9);
myset.add(6);
// Print the values stored in set
console.log(myset);
// Create a new array to store set elements
let myarr = [];
myArray = Array.from(myset)
myArray.sort()
console.log(myArray)
myset.clear()
myset = new Set(myArray);
console.log(myset)
Output
Set(4) { 3, 2, 9, 6 }
[ 2, 3, 6, 9 ]
Set(4) { 2, 3, 6, 9 }
How to sort a set in JavaScript ?
Sorting a Set based on the values of its elements is a common need in JavaScript. While the built-in sort() function can’t be directly applied to a Set, there’s a workaround. Let’s explore how we can achieve this:
Instead of directly sorting the Set, we’ll:
- Convert the Set into an array to make it sortable.
- Utilize the sort() function on the array to arrange its elements based on their values.
- Optionally, convert the sorted array back into a Set if needed.
By following these steps, we can effectively sort the Set according to the values of its elements.
Below are the approaches through which we can sort the set:

- Approach 1: By iterating over the set
- Approach 2. Using Array.from() Method
- Approach 3: Using Spread Operator and Sort Method
