setting a Reset button.

I am trying to set reset button but when I preview it it doesn't work. here is the code for app.js file: const myHeading = document.getElementById('myHeading'); const myButton = document.getElementById("myButton"); const reset = document.getElementById("reset");

myButton.addEventListener('click', () => { myHeading.style.color = 'purple'; }); reset.addEventListner("click", () => { myHeading.style.color = "black";
})

below is the code for 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">Change the color of Heading</button> <button id= "reset">Reset</button> <script src="app.js"></script> </body> </html>

I managed to spot a typo even in the unformatted code:

You wrote "addEventListner" (missing an "e") instead of "addEventListener".

Fix that and it will work.

const myHeading = document.getElementById('myHeading');
const myButton = document.getElementById("myButton");
const reset = document.getElementById("reset");

myButton.addEventListener('click', () => {
    myHeading.style.color = 'purple';
});
reset.addEventListner("click", () => {
    myHeading.style.color = "black";
})

<head>
