In this course, you will learn how to use AJAX to send data to your web server and get response data to output in your web application, as well as how to use JavaScript code to connect to web APIs and retrieve JSON data to output in your webpages. We will start by learning what JSON is and how it works. Following that, we will look at how AJAX can be used by the web browser to make server HTTP requests. Then we will go over AJAX, how to use JavaScript to update DOM elements, and how to modify elements on a webpage by dynamically creating, updating, and styling page elements with code. We will then move on to interactive webpages and go over concepts such as setting up page interactions and adding event listeners. We will cover JSON data and JavaScript objects, arrays, and datatypes, as well as JSON data output and iteration. Finally, we will look at how to create interactive AJAX content with JavaScript objects within webpage content, as well as some examples of popular web APIs. By the end of this course, you will be able to create amazing interactive dynamic applications that can synchronize data between your database and front-end HTML code.
