You
can use the JavaScript™ editor to create, edit, and preview JavaScript files.
The JavaScript editor
also provides features such as content assist, syntax highlighting, and hover
help.
The JavaScript editor provides a Source page and a
Preview page.

The Preview page is only available for Windows
®.
- Source
- The Source page enables you to view and work with a file's source code
directly. The Outline view has features that supplement the Source page.
- Preview
- Preview shows you how the current page is likely to look when viewed
in Microsoft® Internet
Explorer (by default). To preview any dynamic content, you should use the option
from the page's pop-up menu in the Project Explorer view.
