Creating a New Array from a New Set in JavaScript

If you want to create a new array from a new set in JavaScript, there are a few ways to do it. The most common way is to use the spread operator to convert the set into an array.

Using the Spread Operator

The spread operator is a new feature in JavaScript that allows you to expand an iterable object into individual elements. In this case, we can use the spread operator to convert the set into an array.

const mySet = new Set([1, 2, 3]);
const myArray = [...mySet];
console.log(myArray); // [1, 2, 3]

In the example above, we create a new set called `mySet` that contains the values 1, 2, and 3. We then use the spread operator to convert the set into an array and assign it to a new variable called `myArray`. Finally, we log the contents of `myArray` to the console.

Using the Array.from() Method

An alternative way to create a new array from a new set is to use the `Array.from()` method. This method creates a new array from an iterable object.

const mySet = new Set([1, 2, 3]);
const myArray = Array.from(mySet);
console.log(myArray); // [1, 2, 3]

In the example above, we create a new set called `mySet` that contains the values 1, 2, and 3. We then use the `Array.from()` method to create a new array from `mySet` and assign it to a new variable called `myArray`. Finally, we log the contents of `myArray` to the console.

Conclusion

Creating a new array from a new set in JavaScript is easy and can be accomplished using either the spread operator or the `Array.from()` method. Both methods are equally valid and it's up to personal preference which one you choose to use.
