What are the differences between Sets and Maps in JavaScript?
An example of an AI chatbot conversation about comparing Sets and Maps in JavaScript.
What are the differences between Sets and Maps in JavaScript?
Sets and Maps are both collections in JavaScript, but they serve different purposes. A Set is a collection of unique values, while a Map is a collection of key-value pairs.
Can you give me an example of when to use a Set?
Sure! Use a Set when you need to store unique values, like a list of unique user IDs.
And what about Maps? When should I use them?
Maps are great when you need to associate values with keys, like storing user information where the key is the user ID.
Are there any performance differences between them?
Yes, Sets can be faster for operations like checking for existence of a value, while Maps are optimized for key-value pair retrieval.
