Getting Started with JScript
JScript 10.0 represents a major advance of the JScript language in several ways. With tighter integration into the Visual Studio development environment, multiple new features, and access to the .NET Framework classes, moving from JScript to JScript 10.0 may appear at first to be a daunting task.
In reality, almost all of the changes represent additional functionality, while the core JScript functionality is the same as in previous versions. Practically all JScript scripts will run without modification under JScript 10.0 (with the fast mode turned off). To run in fast mode (the mode supported by ASP.NET), some scripts will need minor modifications.
The following documentation will help you to upgrade your applications and quickly understand the changes to JScript 10.0.
