AWS, JavaScript, React - Deploy Web Apps on the Cloud - DOM Manipulation

This video tutorial demonstrates a basic example of DOM manipulation using JavaScript. It begins with an introduction to the concept and then explains the structure of a simple HTML document. The tutorial focuses on a JavaScript function named 'changetext' that alters text within an HTML element. An onclick event is used to trigger this function, changing the text of an H1 element. The video concludes with a demonstration in a web browser, confirming the successful manipulation of the Document Object Model.
