## How to convert a Set to an Array in JavaScript?

November 29, 2021 - 2 min read

To convert a `Set` to an array, you can use the `from()` method from the global `Array` object in JavaScript.

### TL;DR

``````// initialize a set
const uniqueNumbers = new Set();

// add values to the `uniqueNumbers` set

// convert `uniqueNumbers` set to an array
// using the Array.from() method
const uniqueNumbersArr = Array.from(uniqueNumbers);

// log the output of `uniqueNumbersArr` array
console.log(uniqueNumbersArr);

/*

OUTPUT:
-------

[1, 2, 3]

*/
``````

For example, let's say we have a set called `uniqueNumbers` and add some values of `1, 2, and 3` to the set using the `add()` method like this,

``````// initialize a set
const uniqueNumbers = new Set();

// add values to the uniqueNumbers set
``````

Now we have a valid set of unique numbers.

To convert the above `uniqueNumbers` set to an array, we can use the `Array.from()` method and:

• pass the `uniqueNumbers` set as an argument to the method.
• The method returns a new array with all the values of the `uniqueNumbers` set as the array elements.

It can be done like this,

``````// initialize a set
const uniqueNumbers = new Set();

// add values to the `uniqueNumbers` set

// convert `uniqueNumbers` set to an array
// using the Array.from() method
const uniqueNumbersArr = Array.from(uniqueNumbers);
``````

Now we have converted the `uniqueNumbers` set to an array. Yay ðŸŽ‰!

Let's also log the output of the `uniqueNumbersArr` to the console.

It can be done like this,

``````// initialize a set
const uniqueNumbers = new Set();

// add values to the `uniqueNumbers` set

// convert `uniqueNumbers` set to an array
// using the Array.from() method
const uniqueNumbersArr = Array.from(uniqueNumbers);

// log the output of `uniqueNumbersArr` array
console.log(uniqueNumbersArr);

/*

OUTPUT:
-------

[1, 2, 3]

*/
``````

As you see from the above output that the `uniqueNumbers` set is successfully converted into an array in JavaScript.

That's all ðŸ˜ƒ!
