# Set conversion

`Set` collections can be converted to arrays. You can also perform the opposite operation - convert arrays into `Set`. Let's see how it's done.

## Set-to-array conversion

Let we have some `Set` collection:

`let set = new Set([1, 2, 3]);`

You can convert it to an array using the destructuring technique:

`let arr = [...set];`

Or you can use the `Array.from` method:

`let arr = Array.from(set);`

Given a `Set` collection. Convert it to an array in the two described ways.

## Array-to-Set conversion

Let's say we have an array:

`let arr = [1, 2, 3];`

Let's convert it to a `Set` collection:

`let set = new Set(arr);`

Given an array. Convert it to a collection.
