SharePoint JavaScript

SharePoint JavaScript

SharePoint 2013 provides a JavaScript object model for use in either inline script or separate .js files. It includes all the same functionality as the .NET Framework and Silverlight client object models.
the JavaScript infrastructure for SharePoint 2013 interacts with the farm servers in batches. These batches always run asynchronously. In addition, it is now possible to access SharePoint data across domains in JavaScript.
The JavaScript object model is defined in a set of *.js files located at %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\15\TEMPLATE\LAYOUTS on each server.
