What are the advantages of using WeakMaps in JavaScript?

WeakMaps offer several advantages, such as preventing memory leaks, allowing for garbage collection of keys, and providing a way to associate data with objects without preventing them from being garbage collected.

Can you explain how WeakMaps help with memory management?

Certainly! WeakMaps hold weak references to their keys, meaning if there are no other references to a key object, it can be garbage collected, thus helping to manage memory more efficiently.

Are there any scenarios where I should avoid using WeakMaps?

Yes, if you need to maintain a strong reference to the keys or if you require the keys to be iterable, then WeakMaps may not be suitable.

How do WeakMaps differ from regular Maps?

The main difference is that WeakMaps allow for garbage collection of keys, while regular Maps keep strong references, preventing the keys from being collected.
