8. user-event vs fireEvent
Differences between user-event (higher-level) and fireEvent (low-level) for simulating interactions.

user-event vs fireEvent
Two ways to simulate DOM interactions in tests: user-event imitates real user behavior, fireEvent sends low-level events.
"I clicked the button in my test, but nothing happened — why did the event not trigger like in the browser?"
user-event provides high-level, realistic user interactions (typing, clicking, tabbing) that trigger the same sequence of browser events; fireEvent dispatches single, low-level DOM events directly and may miss event sequences or browser-default behavior.
