This book is perfect for intermediate JavaScript developers wanting to take their JavaScript skills to the next level without sacrificing web accessibility or best practice. If you've never written a line of JavaScript before, this probably isn't the right book for you.

If you have only a small amount of experience with JavaScript, but are comfortable enough programming in another language such as PHP or Java, you'll be just fine-we'll hold your hand along the way, and all of the code is available for you to download and experiment with on your own.
