and XML and is a web development technique for creating interactive web applications.
Ajax’s most appealing characteristic is its asynchronous nature, which
means it can do all of this without having to refresh the page. This
allows you to update portions of a page based upon user events. With AJAX,
we only get the data from the server that we absolutely need, not the
whole page. More importantly, data can be posted to and retrieved from the
server after the entire page is loaded. This can be leveraged in creative
and powerful ways to create a more fluid browsing experience. It can send
as well as receive information in a variety of formats, including XML,
HTML, and even text files. The technologies that are used to build AJAX
web applications encompass a number of different programming domains, so
AJAX development is neither as straightforward as regular applications
development, nor as easy as old web development.
