Jul 2, 2024 · Events are things that happen in the system you are programming — the system produces (or "fires") a signal of some kind when an event occurs, and provides a mechanism by which an action can be automatically taken (that is, some code running) when the event occurs.

Feb 3, 2022 · Capturing and bubbling allow us to implement one of the most powerful event handling patterns called event delegation. The idea is that if we have a lot of elements handled in a similar way, then instead of assigning a handler to each of them – we put a single handler on their common ancestor.
