9. It’s deprecated, though: use event.key (“Tab”) or event.code (Tab) in new code.
What is the difference between event.key and event.code?
event.key is the character or action the key produces with the current layout; event.code is the physical key position, the same on every layout.
Should I use keydown or keypress?
keydown. The keypress event is deprecated and doesn’t fire for keys that don’t produce characters, such as Escape or the arrow keys.
