jQuery.supportReturns: Objectversion deprecated: 1.9
Description: A collection of properties that represent the presence of different browser features or bugs; intended for jQuery's internal use.
version added: 1.3jQuery.support
A collection of properties that represent the presence of different browser features or bugs. Intended for jQuery's internal use; specific properties may be removed when they are no longer needed internally to improve page startup performance. For your own project's feature-detection needs, we strongly recommend the use of an external library such as Modernizr instead of dependency on properties in jQuery.support.
As of jQuery 1.11 or 1.12, jQuery.support is no longer JSON-serializable; some properties point to functions that return the support test result when called. This was necessary to support lazy execution of support tests.
