What happens when you call setState () inside render () method?

Why we use event preventDefault () in react?

The preventDefault() method cancels the event if it is cancelable, meaning that the default action that belongs to the event will not occur. For example, this can be useful when: Clicking on a "Submit" button, prevent it from submitting a form. Clicking on a link, prevent the link from following the URL.
