How to convert Set to Array?

Question

Set seems like a nice way to create Arrays with guaranteed unique elements, but it does not expose any good way to get properties, except for generator [Set

Answer 1

if no such option exists, then maybe there is a nice idiomatic one-liner for doing that ? like, using for...of, or similar ?

Indeed, there are several ways to convert a Set to an Array:

using Array.from

let array = Array.from(mySet);

Simply spreading the Set out in an array

let array = [...mySet];

The old fashion way, iterating and pushing to a new array (Sets do have forEach)

let array = [];
mySet.forEach(v => array.push(v));

Previously, using the non-standard, and now deprecated array comprehension syntax:

let array = [v for (v of mySet)];
