Callbacks Quote by Anonymous
““Events complect communication and flow of control. While there are various mechanisms to make events/callbacks cleaner (FRP, Rx/Observables) they don't change their fundamental nature, which is that upon an event an arbitrary amount of other code is run, possibly on the same thread, leading to admonitions such as "don't do too much work in your handler", and phrases like "callback hell".””
About This Quote
Source Article: Software Architecture Patterns, 2020
Events trigger code execution that can cascade, causing handlers to run many tasks, often on the same thread, leading to performance and maintainability issues.
In simple terms: Events cause many actions, which can overload handlers.
Key Takeaway
Keep handlers lightweight and avoid heavy work inside callbacks.
