--description--

In our HTML document, we have a form element with an id attribute: <form id="calorie-form">

To reference and access this particular form in JavaScript, we can use the getElementById() method on the document and provide the ID.

The code document.getElementById('my-form') gets a reference to an HTML element with an id of my-form. Get a reference to the HTML element with the id of calorie-form.
