“This book gives you a thorough introduction to the latest Flash Builder tools and shows how to use the built-in wizards, MXML, or pure ActionScript 3 to build information-rich applications for the browser or AIR applications. Tutorials guide you through each iteration including building user interaction, charting, incorporating audio and video, customizing the UI; and a code repository provides reusable code that you can modify and deploy in your own applications.”
Dr. Dobb’s Developer’s Reading List

Flash has matured into a complete platform, with platform tools, such as Flex, that you can use to build your Web Applications. Cesare explains complex concepts through a careful combination of detailed explanation and visual Projects—transforming the new Flex developer into a master. Flex will not be a mystery by the time you complete this book. — Matthew David

I recommend this book for all the newcomers, and beginner-level Flex developers and to also those who don’t know much about visually appealing Rich Internet Applications
