- Using
Array.from:
Note: safer for TypeScript.
const array = Array.from(mySet);- Simply
spreadingthe Set out in an array:
Note: Spreading a Set has issues when compiled with TypeScript (See issue #8856). It’s safer to use Array.from above instead.
const array = [...mySet];- The old-fashioned way, iterating and pushing to a new array (Sets do have
forEach):
const array = [];
mySet.forEach(v => array.push(v));- Previously, using the non-standard, and now deprecated array comprehension syntax:
const array = [v for (v of mySet)];Convert Set to Array JavaScript
Simple example code several ways to convert a Set to an Array:
<!DOCTYPE html>
<html>
<body>
<script>
var s = new Set([2, 4, 6, 8]);
console.log(Array.from(s));
console.log([...s])
let arr = [];
s.forEach(x => arr.push(x));
console.log(arr)
</script>
</body>
</html>Output:
