Course Summary
AJAX is a technology that allows a webpage to communicate to and from a server/database without the need for a complete page refresh. Google’s Gmail is famous for being one of the first major applications to leverage AJAX (in 2004) to offer a better user experience. The JavaScript Data, Ajax, and REST course teaches developers to use AJAX and Representational State Transfer (REST) properly to fetch, change, and retrieve data within a web application.
The course begins with a review of AJAX and the browser's AJAX objects. Next, the course examines REST architecture and the ways in which RESTful data can be loaded through various JavaScript Frameworks, followed by explanations of how browsers handle and transfer files to servers. The course concludes with an exploration into how to construct a simple RESTful API using Node.js. The course would be valuable for developers and developer teams who use AJAX regularly and wish to more thoroughly explore its Application Programming Interface (API).
