What are the differences between Map and WeakMap?
An example of an AI chatbot conversation about Map vs WeakMap in JavaScript.
Can you explain the differences between Map and WeakMap in JavaScript?
Sure! Both Map and WeakMap are collections for storing key-value pairs, but they have some key differences.
What are the main differences in terms of key types?
In a Map, keys can be of any type, including objects. In a WeakMap, keys must be objects, and they are weakly held.
What does 'weakly held' mean?
'Weakly held' means that if there are no other references to the key object, it can be garbage collected, preventing memory leaks.
Are there any performance differences between them?
Yes, WeakMap can be more memory efficient for certain use cases, especially when dealing with large datasets and object references.
