Visualizer is the command-line interface for building web applications.
Visualizer offers a number of features to help you quickly write code in the Visual Basic programming language.
VBscript, on the other hand, is a scripting language that can be used to write scripts for many common computer-based applications, such as games, web applications, and database servers.
It is easier to learn and more flexible than Visualizer.
