Course description

AJAX stands for Asynchronous JavaScript and XML. AJAX is a method used to create fast and dynamic web applications with the help of XML, HTML, CSS, and JavaScript. With Ajax, web applications can send and retrieve data from a server asynchronous without interfering with the display and behavior of the existing page.

Ajax makes the features like drop-down menus, predictive text, auto-filled text, and more possible. AJAX allows the web pages to be efficient asynchronously by exchanging small amounts of data with the server behind the scenes. This means that it is possible to update parts of a web page, without reloading the page.

Elysium Academy Private Limited, AJAX training, and certification course will teach about AJAX starting from AJAX features, fundamentals to creating AJAX programming. All the features offered in the AJAX certification course will develop your programming ability and make you an expert in the field.
