browser ⟩ event ⟩ propagation
the process by which the browser decides which objects to trigger event handlers on.
3 phases of event propagation:
(“capturing” phase) occurs before the target handlers are invoked.
target handlers invoked.
(“bubbling” phase) event bubbling.
most events to the object, and then to the object, notable exceptions are the “focus” “blur,” and “scroll” events.
The capturing phase is like the bubbling phase in reverse.
capturing handlers of the object are invoked first.
