AWS, JavaScript, React - Deploy Web Apps on the Cloud - JavaScript Events

The video tutorial explains how to use JavaScript events to execute code in response to user actions. It covers common events like mouse clicks, mouseovers, and mouseouts, using a sample HTML file with a button element. The onclick event is demonstrated to display the current date and time when the button is clicked.
