Raphael.JS is a SVG/VML library which helps you to create quick vector shapes and images. Its very small and compact (only 86kb),easy to use,well documented and works in all browsers and yes even IE. Here is a list of all major browsers this library works on: Chrome 5.0+ Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+ ,finally its distributed under MIT license. In this tutorial ,I intend to introduce basics of this library and help you get started.

I love JavaScript and code a lot in it .Since I code, I also encounter problems and bugs from time to time and therefore need a Debugger and a debug mechanism to view whats going on. In good old days when I learned this language, I used JavaScript’s inbuilt alert mechanism to view the value of a variable or a property of an object. This was a terrible mechanism, calling alert was blocking, one had to press OK to continue and if you had to take a look inside an array then well it was emotionally an overwhelming task is all I would say here.

HTML5 WebSockets, defines a full-duplex communication channel that operates through a single socket over the web. WebSocket is not just another incremental enhancement to conventional HTTP communications, it represents a large advance, especially for real-time, event driven web applications. Normally when a browser visits a web page, an HTTP request is sent to the web server that hosts that page. The web server acknowledges this request and sends back the response.

Here is another of many JavaScript based Image Carousel, I had seen many similar to these made in SilverLight and Flash, I came across a wonderful carousel made in SilverLight sometimes back which was very fluid in behavior and could easily be customized and configured to take various shape and form. I have managed to port it to JavaScript, it works best on chrome or FF, hope this would be fun to play with.

One of the amazing features of i-phone user interface is smooth panning/scrolling animation. I-phone “List Scrolling” perhaps gives a very funky and usable List –View to its users and allows them to scroll up and down the interface without any need of a scroll bar. This interface is sensitive to the push speed and also shows traces of resilience. I have been experimenting with various techniques to bring out similar effect using JavaScript and HTML, I am not quite sure if this would be useful in its present form but with some modifications may be this sample could prove its worthiness somewhere.
