3,050 PointsMy code isnt working- please review
<!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> <script src="app.js"></script> //verified this is linked by adding an alert </body> </html>
const myHeading = document.getElementById('myheading');
myHeading.addEventListener('click', () => {
myHeading.style.color = 'red';
});
JS console error: Uncaught TypeError: Cannot read property 'addEventListener' of null at app.js:4
The click function to change the heading to red from black isn't working (from: JS > Javascript and the DOM > Getting a handle on the DOM > A Simple Example)
Thank you.

<h1 id="myHeading">
document.getElementById('myheading');

Courses Plus Student 11,987 PointsYou looked at this wrong. Rod was just copying and pasting his code to the post without using the backtick. So it's hard to read. The first answer is right he did a typo.
