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.
