Ajax, WebSocket, WinRTC and server-client applications

Asynchronous JavaScript and XML is a technology that changes the way web pages work, allowing you to supplement them with exchanges in asynchronous mode with the server. It also makes it possible to create online applications.

The name Ajax was launched by Jesse James Garrett in an article published on the Adaptive Path website in 2005 and the translation of which is provided by .fr as of May 6, 2006. This is a combination of existing technologies for creating dynamic websites and with the main component, the XMLHttpRequest JavaScript object, which allows you to interact with the server asynchronously.

Ajax remains the best solution for updating web content at the user's request, but is being replaced by WebSocket and WebRTC to create interactive online or local applications on a client-server model. These technologies are also the topic of this section .
