As an absolutely beginner with no knowledge in JavaScript, I find this book highly valuable. I was able to follow step by step in an easy format. This 332 pages book was very detailed, thorough and had lots of examples. I highly recommend this book for beginners and/or those who is looking to freshen their skills. This book is definitely a keeper.
