Objects (Visual Studio - JScript)

JScript objects are collections of properties and methods. The following sections link to information that explains how to use JScript objects.


The JScript runtime is not designed to be thread-safe. Consequently, JScript objects and methods may have unpredictable behavior when used in multithreaded applications.
