I was asked to review this book. I feel the book is really good for beginners. The examples provided by the author are simple, easy to understand and to implement, not to mention serve as a good reference to build upon.

The first 6 chapters are all about the HTML5 Canvas and how to make the best use of it. The later ones give a peek into 3rd party libraries, Google charts and maps. It was impressive to see the amount of work some people have done using Canvas and it's "relatives"!

By going through the examples of the book, you end up doing a bit of Mathematics yourself. This helped me brush up some of my Math skills, especially Trigonometry. (Perks?)

The example in the book has some bugs (eg: Chapter 3, Building a bar chart from scratch: The chartYData.value are in decimals but the range.max is 10; the chartYData should be whole numbers), but the code samples make up for it.

My biggest gripe about the book is that, there is not one line in the book that told me what getContext actually does. The book could have also included some of the advanced/other concepts like toDataURL().

All in all, this is a good book to start off with to learn about HTML5 Canvas.… (más)
