You have an absolute bound on the number of chapters, and each has to be simple enough to be absorbed in an hour. Hemmed in by those limitations, this book cannot be exhaustive, in terms of a reference to the language, but Moncur does an excellent job within those restrictions, and has produced a very serviceable and useful introduction to JavaScript. Part one addresses getting started.
Chapter one gets off to a bit of a rocky start with several errors.
The book says that JavaScript was renamed from LiveScript to reflect its relationship to Java, and then points out that there is no such relationship. A note refers to a title that it doesn't have, pointing out some careless editing. Moncur also says that scripts in headers are not executed immediately, which is wrong. The chapter does end with a simple beginner script that will print out a message. This is expanded, in chapter two, to a simple script with some calculations.
