I'm confused after reading the documentation for both react and some HTML stuff about how on click event handling should work.

For buttons, for example a button that onClick will dispatch an action to submit a form, is a preventDefault necessary?

Thanks

The event.preventDefault() method stops the default action of an element from happening.

In your case, prevent a submit button from submitting a form.
Another example - prevent a link from following the URL.

So it is preferred to use it on onClick method. It'll stop a form from automatically submitting the form.
