Frequently Asked Questions

What's the difference between key and code?

event.key represents the character ("a" or "A"), while event.code represents the physical key ("KeyA") regardless of layout.

Why is keyCode deprecated?

keyCode is deprecated because it varies between browsers and keyboard layouts. Use event.key or event.code instead.
