For example, this form in plain HTML accepts a single name: This form has the default HTML form behavior of browsing to a new page when the user submits the form. But in most cases, it’s convenient to have a Java Script function that handles the submission of the form and has access to the data that the user entered into the form.

We can also plug in the .prevent modifier to prevent the default action, which in this case would be the page refreshing when the form is submitted: In the above example, we simply log the entire form model to the console on form submission.
