In JavaScript, if you want to convert a Set (collection) into an Array array, you can do it in the following way.

Method 1: Use the spread operator (three-dot operator) " ... "

Using the spread operator "..." can also help us convert a Set into an array.

Syntax:

var variablename = [...value];

Example:

<script> 
       const set = new Set(['HELLO', 'JS']); 
       console.log(set);
       const array = [...set]; 
       console.log(array); 
</script>

Method 2: Use the Array.from() method.

The Array.from() method returns a new array from an object or iterable object (such as Map, Set, etc.).

Syntax:

Array.from(arrayLike object);

Example:

<script> 
     const set = new Set(['welcome', 'you','!']); 
     console.log(set);
     console.log(Array.from(set))
</script>
