How do JavaScript collections compare to each other?
JavaScript has several collection types like Arrays, Sets, and Maps. Each has unique features and use cases.
What are the main differences between an Array and a Set?
Arrays are ordered and can contain duplicates, while Sets are unordered and only store unique values.
When should I use a Map instead of an Object?
Use a Map when you need key-value pairs with any type of key, while Objects are best for string keys.
Can you give an example of when to use a Set?
Sure! Use a Set when you want to store unique items, like a list of unique user IDs.
