How to Create a JavaScript Key Listener?

Estimated read time 1 min read

A key listener in JavaScript allows you to detect and respond to user keyboard events in a web page. To create a key listener, you can use the “keydown” event of the document object. Here’s an example:

document.addEventListener("keydown", function(event) {
  console.log("Key pressed: " + event.key);

In this example, the keydown event is attached to the document object, and a callback function is executed every time a key is pressed. The event.key property returns the value of the key that was pressed. The output will be logged to the console, so you can see the result in your browser’s developer tools.

Please note that using this code only allows you to detect and respond to keyboard events, and it is not intended to be used for unethical purposes.
