This section provides an overview of a typical Web scripting processing flow architecture showing server-side and client-side scripting steps.
As we can see from previous chapters, JavaScript code can be used in three areas to help building
Web sites or Web based applications:
Server-Side Scripting - Scripts embedded in HTML documents to be processed by the Web server
before sending to the client - Web browser.
Server-side scripting usually used to interact with database or other backend applications and
to bring dynamic data into HTML documents.
Client-Side Scripting for Page Document Building - Scripts embedded in HTML documents to be processed
by the Web browser before rendering the page document on the browser window.
Client-Side Scripting for Browser Event Handling - Scripts embedded in HTML documents to be processed
by the Web browser when user interacts with the Web browser window.
The diagram below shows you how server-side scripting and client-side scripting can be
used together performing different functions in a typical Web application process flow architecture:
Red lines used in this diagram indicate where JavaScript could be used.
Different sections of this Web scripting flow architecture diagram will be explained later.
