How to find out what character key is pressed with JavaScript?

You can find out which character key is pressed in JavaScript by listening for the keypress event on an element and accessing the charCode property of the event object. The charCode property returns the Unicode character code of the key that was pressed.

Here’s an example:

document.addEventListener('keypress', function(event) {
  console.log(String.fromCharCode(event.charCode));
});

In this example, we attach an event listener to the document object to listen for the keypress event. When the event is triggered, we access the charCode property of the event object and use the String.fromCharCode() method to convert the Unicode character code to a string. Finally, we log the resulting string to the console.
