Book Reviews: JavaScript: The Good Parts, by Douglas Crockford; JavaScript Enlightenment, by Cody Lindley; DOM Enlightenment, by Cody Lindley
I asked a colleague whether I might borrow the first of these books, and was subsequently offered all three. They are all quite slim, but JavaScript: The Good Parts in particular is rather dense, and I rather doubt it has all sunk in. However, I have certainly improved my understanding of the language. The problem is that JavaScript is something that is easy to make work, even when what you have written is "wrong" or at least, not exactly what you intended. So I am clearer on variable scope, prototypes, the meaning of "this" in different contexts, and possibly even closures. Of the three, JavaScript Enlightenment was the most straightforward for me. A cautionary tale about DOM Enlightenment - the author points out that he is discussing an "idealized DOM", i.e. not one that may be universally available in all browse environments. Nevertheless it does shed quite a bit of light on what jQuery is doing at least some of the time.
