Dear Zakas,
first of all,tks your book!it is so great.
I'm a junior jAVA developer from China.before your book i'v read many other books about JS XML and others ,but those helped me less. i'v got your book which is tranlated into simple Chinese just 2 weeks ago.i found what i needed from this book,not only JS but OOP REG and XML.it was so easy to know,as far as know this book is the best for me.
PS: please forgive my poor english express:)
