Why did VS Code cross out the keyCode property?

Question

Visual Studio Code

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

Answer 1

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

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

Krch saying use key instead of keyCode if you can
PS But don't care, js will pull this load to ensure compatibility with old code

Answer 2

Because this property is deprecated and its use is not recommended.

Answer 3

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