What are sets and iterators in JavaScript?

Can you explain what sets are in JavaScript?

Sure! In JavaScript, a Set is a collection of unique values. It can store any type of value, whether primitive or object.

How do I create a Set and add values to it?

You can create a Set using the new Set() constructor. To add values, use the add() method. For example: let mySet = new Set(); mySet.add(1);.

What are iterators and how do they work with Sets?

Iterators are objects that allow you to traverse through a collection. Sets have a built-in iterator that you can use with a for...of loop to access each value.

Can you show me an example of using an iterator with a Set?

Absolutely! Here's an example:

let mySet = new Set([1, 2, 3]);
for (let value of mySet) {
    console.log(value);
}
``` This will log 1, 2, and 3 to the console.
