About this deal
This Chapter is all about events: what they are, how they work, and the different kinds of events you’ll encounter. I would have liked to see some coverage of test driven development (Fireunit, JSSpec, jsmock ) but that may be getting greedy for an intro book plus I have yet to see it in other Javascript books I've browsed.
We set out to compare the biomechanical effect of S2AI versus traditional iliac screw fixation on S1 screw strain.Prepare to open your mind as you learn (and nail) key topics including: The inner details of JavaScript How JavaScript works with the browser The secrets of JavaScript types Using arrays The power of functions How to work with objects Making use of prototypes Understanding closures Writing and testing applications What's so special about this book? Now I can see that it’s more in-depth and more informative than Head First, but it’s difficult to begin learning JS from it without any previous experience or general understanding. Ebenfalls ein Rätsel ist das Kapitel über Debugging und Troubleshooting, denn den Inhalt dieses Kapitels könnte man auf einige wenige Seiten zusammenkürzen.

I have already begun work on a couple of javascript projects and am making excellent progress thanks to the solid foundations laid by working through this book. The second one was titled ‘Scoop and Closures,’ which discuss the rules that JS compile follows to determine where and how a variable in your code can be looked-up, and how a function is able to remember and access its scope even when it’s executing outside it (and this is a Closure).But don't be fooled; you might be having a good time while you're learning JavaScript, but you're still learning all the serious stuff. Once you get over the non-traditional presentation, the books are actually fun to read and work the exercises, helping to instill the concepts. Wer noch nie zuvor mit C++ oder Java programmiert hat, für den ist "Head First JavaScript" sicherlich ein guter Einstieg, aber wer bereits Programmiererfahrung hat, der sollte sich für David Flanagans Referenzwerk entscheiden.
