HI Trevor Burnham:

I'm a reader of your Async JavaScript book, I bought it on 23rd March and finished it on 26rd March, it is really a treasure to me, probably the best book about async programming in JavaScript I have ever read.

After finished this book, I found there are a few problems, as well as a set of my questions, exists, so I wrote this mail to you, expecting you could give a brief look.

Since I'm not a native English speaker, my English is really poor, so if there is any ambiguousness, please feedback to me so I could have a change to state it more clearly.

Fist of all, I would like to list 9 problems I found in this book, most of which are produced by the difference between our perspectives, so feel free is you don't think they are problems.
