arrow_back Why did VS Code, cross out the keyCode property?

Question

The code works as intended, no errors or warnings from the compiler. So what's the problem?

Answer 1

Because if you go to https://developer.mozilla.org/ru/docs/Web/API/Docu...
Then in front of the keyCode we will see

Warning: This attribute is deprecated; you should use key instead, if available.

In short, use key instead of keyCode if you can
P.S. Whatever, js will pull this load to ensure compatibility with the old code

Answer 2

KeyboardEvent.KeyCode is deprecated. You can use KeyboardEvent.code

https://developer.mozilla.org/en-US/docs/Web/API/K...

Answer 3

Because this property is in a derriere status and its use is not recommended.
