I sponsor a high school computer programming club and my students had me pre-order this book for them, as they loved the Head First HTML book and felt this would be their best bet at really understanding JavaScript.

JavaScript is a strange language to teach. Although you want to teach the basics of programming, you also want to have early exciting examples that show its possibilities when embedded in a web page. This book does about as well as can be done in one book, with sections on loops, decision making, de-bugging, functions and objects for those new to programming. Then there are also chapters on the most common uses of JavaScript, including, of course, forms and validation.

If you're familiar with the Head First approach, you will find this book to fit in perfectly with their other titles. This is the kind of book you buy, highlight, and write in. Active learning. This is not a reference book.
