const form = document.querySelector('form');
const submitButton = form.querySelector('[type=Submit]');

form.addEventListener('submit', () => {

index.html
<!DOCTYPE html>
<html>
<head>
  <title>Submit Event</title>
</head>
<body>
<form>
  <label>Name:</label>
  <input type="text" name="name">
  <input type="Submit" name="submit" value="Submit">
</form>
  <script src="app.js"></script>
</body>
</html>

Don't forget about the methods of the event object.

If you pass the event object to the handler, you can then call the preventDefault method on it.

I'll bet you can solve the challenge now without an explicit spoiler.

Complete coverage of the methods and properties available on an event object can be found on the MDN documentation page.

This is the correct code:

form.addEventListener('submit', (event) => {
  event.preventDefault();
});

Try This!

form.addEventListener('submit', (e) => { e.preventDefault(); });
