What are the common mistakes in the Observer pattern?

What are the common mistakes in the Observer pattern?

Some common mistakes include not properly managing subscriptions, failing to notify observers, and creating tight coupling.

Can you explain how to manage subscriptions effectively?

To manage subscriptions effectively, ensure that observers can easily subscribe and unsubscribe, and avoid memory leaks.

What is tight coupling, and why is it a problem?

Tight coupling occurs when components are heavily dependent on each other, making the system less flexible and harder to maintain.

How can I avoid these mistakes in my implementation?

You can avoid these mistakes by following best practices, such as using weak references for observers and implementing a clear interface.
