how to see if user clicked key in js

document.addEventListener("keyup", function(event) {
    if (event.keyCode === 13) {
        alert('Enter is pressed!');
    }
});

Here is what the above code is Doing:
1. We are adding an event listener to the document.
2. The event listener is listening for a keyup event.
3. When the keyup event is triggered, the event listener will call the function that is passed to it.
4. The function that is passed to the event listener will check to see if the key that was pressed was the enter key.
5. If the key that was pressed was the enter key, then an alert will be displayed.
