Client Side Coding

• Ajax Asynchronous JavaScript provides new methods of using JavaScript, and other languages to improve the user experience.
• Flash Adobe Flash Player is an ubiquitous browser plugin ready for RIAs. Flex 2 is also deployed to the Flash Player (version 9+).
• JavaScript Formally called ECMAScript, JavaScript is a ubiquitous client side platform for creating and delivering rich Web applications that can also run across a wide variety of devices.
• JQuery Cross-browser JavaScript library designed to simplify and speed up the client-side scripting of HTML.
• Microsoft Silverlight Microsoft's browser plugin that enables animation, vector graphics and high-definition video playback, programmed using XAML and .NET programming languages.
• Real Studio Web Edition is a rapid application development environment for the web. The language is object oriented and is similar to both VB and Java. Applications are uniquely compiled to binary code.
• HTML5 and CSS3 Latest HTML proposed standard combined with the latest proposed standard for CSS natively supports much of the client-side functionality provided by other frameworks such as Flash and Silverlight

Looking at these items from an "umbrella approach", client side coding such as XHTML is executed and stored on a local client (in a web browser) whereas server side code is not available to a client and is executed on a web server which generates the appropriate XHTML which is then sent to the client. The nature of client side coding allows you to alter the HTML on a local client and refresh the pages with updated content (locally), web designers must bear in mind the importance and relevance to security with their server side scripts. If a server side script accepts content from a locally modified client side script, the web development of that page is poorly sanitized with relation to security.
