Handling events
JavaScript events are invoked when a user interacts with a web app. For example, when a user clicks a button, a click
event will be raised from that button. We can implement a JavaScript function to execute some logic when the event is raised. This function is often referred to as an event listener.
Important Note
In JavaScript, event listeners are attached to an element using its addEventListener
method and removed using its removeEventListener
method.
React allows us to declaratively attach events in JSX using function props, without the need to use addEventListener
and removeEventListener
. In this section, we are going to implement a couple of event listeners in React.

component. Follow these steps...
