These are some of the benefits of the Observer pattern:
- Dynamism: The Observer permits the Subject to add as many objects as it necessitates as Observers. But it can also remove them dynamically at runtime.
- One-to-Many: The main benefit of the Observer pattern is that it elegantly solves the problem of implementing an event handling system in which there's a one-to-many relationship between objects.
The following are some potential drawbacks of the Observer pattern:
- Disorder: The Observer pattern doesn't guarantee the order in which Observers get notified. So, if two or more Observer objects share dependencies and must work together in a specific sequence, the Observer pattern, in its native form, is not designed to handle that type of execution context.
- Leaking: The Observer can cause memory leaks as the subject holds strong references to its observers. If it's implemented incorrectly and the Observer...
