How to Sort Items of a Set in JavaScript ?

Answer

To sort items of a Set in JavaScript, you can convert the Set to an Array and use the sort() method.

✐ Examples

1 Sort Items of a Set of Numbers

In this example,

We create a Set named numberSet with a set of numeric values.
We convert the Set numberSet to an Array using the Array.from() method.
We then use the sort() method to sort the items in ascending order. The sort() method without a compare function sorts the array elements as strings.
To ensure numeric sorting, we pass a compare function (a, b) => a - b to the sort() method.
Finally, we print the sorted array to the console.

JavaScript Program

const numberSet = new Set([5, 3, 8, 1, 2]);
const sortedArray = Array.from(numberSet).sort((a, b) => a - b);
console.log("Sorted array:", sortedArray);

Output

Sorted array: [1, 2, 3, 5, 8]

2 Sort Items of a Set of Strings

In this example,

We create a Set named stringSet with a set of string values.
We convert the Set stringSet to an Array using the Array.from() method.
We then use the sort() method to sort the items in alphabetical order. The sort() method without a compare function sorts the array elements as strings by default.
Finally, we print the sorted array to the console.

JavaScript Program

const stringSet = new Set(["banana", "apple", "cherry", "date"]);
const sortedArray = Array.from(stringSet).sort();
console.log("Sorted array:", sortedArray);

Output

Sorted array: ["apple", "banana", "cherry", "date"]
