I recently accepted Packt Publishing 's invitation to review Rami Sarieddine 's book Developing Windows Store Apps with HTML5 and JavaScript .

This book is geared towards people who already know at least a little HTML and CSS and now want to add interactivity to their web sites, make web-based apps, or just learn some programming basics.

jsFiddle lets developers play with the three core elements of Web development. Check out this powerful application for rapid prototyping and testing.
