    this.handleEnter = this.handleEnter.bind(this);
    this.handleKeyPress = this.handleKeyPress.bind(this);
  // change code below this line
  componentDidMount() {
     document.addEventListener("keydown", this.handleKeyPress)
  componentWillUnmount() {

Link to the challenge:

In your querySelector use .yourClassName for class, #yourId for id. Fix that and it works fine.


I tried to fix as per id and class but still my pen not giving the output, what is wrong now? Thanks.:slight_smile:

It works for me, you have the correct code. Click on the white area so the focus is in your app, and not in your code, and hit enter.

If it is not working maybe it is a browser issue? I’m using Firefox.

Oh Yes!! I hit on the white area and it worked!! Thanks a ton !!! Really appreciate your suggestion!
