The "AJAX for Web Developers" course explores how modern websites update parts of a web page without the need to reload the entire page, providing a fluid and fast user experience. This course covers the relationship between client apps or websites and servers, the distinction between full page loads and AJAX, and the best use-cases for each. We will delve into Javascript's Fetch API, modern Async/Await syntax, and the benefits of using the Axios module to streamline the process of making requests to a server and handling the response. The course also introduces JSON as a data exchange format for clients and servers, explaining how to encode and decode JSON, error-handling for AJAX requests, and crucial security best practices for AJAX. By the end of the course, you'll be ready to interact confidently with a live API and update elements on the page via AJAX.
