Ajax is a term that has multiple uses, although it is not part of the dictionary prepared by the Royal Spanish Academy ( RAE ). It could be, for example, the name of a famous Dutch football team.

AJAX in computing
When the concept appears written in capital letters ( AJAX ), it is an acronym that, in Spanish, refers to the expression Asynchronous JavaScript And XML . AJAX , in this framework, is a technique that is used in the field of computing for the development of interactive web applications. AJAX applications have the particularity of running in the Internet browser or Web browser simultaneously with the communication between the browser and the server ( Web server ) that takes place in the background.
It is important to understand that AJAX is not a single technology , but a combination of several, and that it has existed for many years. Among the languages that merge to give rise to AJAX programming are XML, Javascript, HTML and CSS.
Thanks to an implementation of this type we can achieve results of a dynamism impossible with HTML alone, for example. The secret is that, unlike an old website, in which once a page finishes loading on the client's computer it no longer downloads information from the server, AJAX is capable of maintaining constant communication without completely refresh the page, as if it were a silent update of the contents .
Chrome is a browser that allows the technologies included in AJAX.
Acronym details
Let's see below the explanation of each of the parts of this acronym:
- Asynchronous refers to the fact that, from the moment the client requests information from the server until the response arrives, the page does not stop working, but rather the experience continues normally and, generally, the user can continue interacting with the rest of the users. elements, including overriding your request (for example, closing a pop-up box in which the communication status was displayed). As soon as the exchange between the server and the client is completed, a response is prepared "behind the scenes", which finally generates the desired change in the content (for example, moving from the "News" section to "Store").
- Javascript is the language used to instantiate an AJAX type response , analyze its content and finally update the DOM (the "Document Object Model" , that is, the interface with which the representation of web documents is possible. , XML and XHTML ).
- To make the request to the server , the client uses the XMLHttpRequest or XHR API . An API ( "Application Programming Interface ") is a series of methods used to specify communication rules between two parties. It is important to note that the response is not required to be in XML , but can be in any format.
