Why isnt my heading turning red ?

app.js

const myHeading = document.getElementById('myHeading');

myHeading.addEventListener('click', () => { myHeading.style.color = 'red'; });

index.html

<!DOCTYPE html> <html> <head> <title>JavaScript and the DOM</title> <link rel="stylesheet" href="css/style.css"> </head> <body> <h1 id="myHeading">JavaScript and the DOM</h1> <p>Making a web page interactive</p> <button id="myButton">Make heading red</button> <script src="app.js"></script> </body> </html>

It does turn red if you click on the heading itself, because that's what the click event handler is attached to.

Did you intend to attach it to the button instead? That change is made later in the video.
