What are some examples of sets in JavaScript?
An example of an AI chatbot conversation about using sets in JavaScript.
Can you give me some examples of sets in JavaScript?
Sure! In JavaScript, a Set is a collection of unique values. For example, you can create a set like this: const mySet = new Set([1, 2, 3, 4, 4]); This will only store the unique values 1, 2, 3, and 4.
How do I add values to a set?
You can add values using the add method. For example: mySet.add(5); will add the value 5 to the set.
What happens if I try to add a duplicate value?
If you try to add a duplicate value, the set will ignore it. For instance, adding 4 again won't change the set.
Can I convert a set back to an array?
Yes! You can convert a set to an array using the spread operator: const myArray = [...mySet]; This will give you an array of the unique values.
