A common need on a Web page that contains a form is to reset it to the original state.

I think that some time ago many forms had a “reset” button, although now I see it being used less and less.

The reset button is an input element with type="reset":

<input type="reset" />

You can programmatically reset a form using JavaScript, too.

All you need is the form element reference:

const form = document.querySelector('form')

and then you can call the reset() method on the it:

form.reset()

This will clear all the elements in the form, restoring them to the original state.
