Model-View-Controller development style: Visualforce adheres to the MVC pattern by providing the view of the application in the Force.com platform. A view is defined by user interfaces and Visualforce markup. The Visualforce controller, which can be associated with Visualforce markup, takes care of the business logic. Therefore, the designer and the developer can work separately. While the designer focuses on the user interface, the developer focuses on business logic.

User-friendly development: A developer (with an administrator profile) user can have a Visualforce editor pane at the bottom of every Visualforce page. This editor pane is controlled by the Development Mode option of the user record. This feature allows us to edit and see the resulting page at the same time and in the same window. This Visualforce editor has the code-saving features of autocompilation and syntax highlighting.
