What is AJAX?

AJAX is not a programming language or a tool, but a concept. AJAX is a client-side script that communicates with a server / database without the need for a callback or a full page refresh.  Ajax itself is a generic term for a variety of JavaScript Techniques, mostly used to dynamically connect to a web server without loading multiple pages. In a narrower defined sense, it refers to the use of XmlHttpRequest objects to dynamically interact with a web server through JavaScript.

Where should AJAX be used?

• AJAX allows web pages to be updated in a serial manner, exchanging a very small amount of data with the server. This means that certain parts of the entire web page can be updated without having to reload. This speed feature from Ajax improves the performance of browsers and provides an advanced user experience.
• AJAX uses scripting to communicate with its server and exchange data using JavaScript. The response time of this file is very fast. This, in turn, leads to increased speed and performance. With AJAX, network load is reduced on both sides.
• AJAX compatible with many commonly used languages, such as PHP, J2EE, ASP.NET.
• It is supported by almost all major browsers, including Internet Explorer 5 and higher, Opera 7.6 and higher, Mozilla Firefox 1.0 and higher, Apple Safari 1.2 and higher.
• For AJAX, you must first have a good knowledge of JavaScript. But learning Ajax is not difficult. You can apply Ajax in a meaningful way with a short-term work. It is open source.
• Asynchronous data processing is possible with XmlHttpRequest, the cornerstone of AJAX applications. In this way, requests are handled more efficiently, while dynamic content loading performance is significantly improved.
