How do I detect the KeyboardEvent for the escape key? [duplicate]

Question

Whether the fact that a lot of features have been deprecated or are not part of the current standard for the KeyboardEvent object class. Was just wondering why whenever I press either shift or esc. Non of the keys show up on my console for Chrome or Mozilla.

document.addEventListener("keypress", (e) => {
    console.log(e.keyCode);
    console.log(e.key);
    console.log(e.code);
    console.log(e.shiftKey);
});

Answer 1

keypress is only triggered when a printable character is pressed. For all keys, you need to work with keyup or keydown.

From MDN:

keypress

The keypress event is fired when a key that produces a character value is pressed down. Examples of keys that produce a character value are alphabetic, numeric, and punctuation keys. Examples of keys that don't produce a character value are modifier keys such as Alt, Shift, Ctrl, or Meta.

document.addEventListener("keydown", (e) => {
    console.log(e.keyCode);
    console.log(e.key);
    console.log(e.code);
    console.log(e.shiftKey);
});
