Tiff, very, very, very well written. Ross and I couldn’t have reviewed our own book any better. I’m glad you took the time to read through it and write such a detailed explanation of what the book is all about. This was definitely spot on and we both greatly appreciate your kind words in this review.

Sounds like a book that I might have to check out. Thanks for the review.

Javascript is a functional and not OO language. A lot of folks coming over from the server-side will to try implement OO patterns, inheritance, and multitude of abstract classes.

When you add all these OO layering, it creates complexity, slow execution, hard to trace errors, and even extend development time!

In my opinion, JQuery has the better use and approach to JS libraries than Prototype. I bring this up because each library has contrasting approaches.

Even Peter Paul Koch of prefer just writing simple functions over any OO Libraries out there.

it’s comments like yours that misrepresent JavaScript. If you even took a peak behind what drives jQuery, you’d see that it’s completely written with an object oriented design.

Regarding PPK, despite his brilliance and my own love for his work, most of his JavaScript has been written for small independent websites, not necessarily for full blown web applications like GMail, Docs and Spreadsheets. Had he needed to plan for building a web app, you’d probably see a shift in his own style.

Saying something like “Javascript is a functional and not OO language” is a complete ignorant statement. The fact is, it’s both ;)

I should be more clear in saying Javascript is not a class-based OO language like Java/C but a prototype-based object language.
