What are some common use cases for map and object in programming?

Maps and objects are often used for storing key-value pairs. For example, you can use a map to store user data where the user ID is the key.

Can you give me more examples of when to use a map over an object?

Sure! Use a map when you need to maintain the order of entries or when keys are not strings. For instance, if you're tracking unique items.

What about performance? Is one better than the other?

Maps generally offer better performance for frequent additions and removals of key-value pairs, while objects are faster for static data.

Are there any limitations to using maps?

Yes, maps cannot use objects as keys directly, and they have a slightly larger memory overhead compared to objects.
