Introduction to AJAX

What is AJAX?

  • AJAX is an acronym for Asynchronous JavaScript and XML.
  • It is a group of inter-related technologies like java script, DOM, XML, HTML/XHTML, CSS, XMLHttpRequest etc.
  • AJAX allows us to send and receive data asynchronously without reloading the web page. So it is fast.
  • AJAX allows us to send only important information to the server not the entire page. So only valuable data from the client side is routed to the server

side. It makes our application interactive and faster.
