The DOM also provides access to user actions such as pressing a key and clicking the mouse. It is possible to intercept and process these and other events by creating event handler functions and routines.

Other key aspects include event loops, event queueing and prioritization, event sourcing, and complex event processing patterns. These mechanisms contribute to the flexibility and scalability of event-driven systems.
