You download a tarball, compile and install the source.It let's you run JavaScript programs by typing 'node my_app.js' in your terminal.The JS is executed by the V8 javascript engine (the thing that makes Google Chrome so fast).Node provides a JavaScript API to access the network and file system "But I can do everything I need in: ruby, python, php, java, ... !". I hear you. "Get to the point!" Alright, I will. "Huh?" That's right, everything runs in parallel, except your code.

Underlying these containers is a common pattern to how they perform the wiring, a concept they refer under the very generic name of "Inversion of Control". In this article I dig into how this pattern works, under the more specific name of "Dependency Injection", and contrast it with the Service Locator alternative.

Advanced Web Applications With Object-Oriented JavaScript Recently I interviewed a software developer with five years experience in developing Web applications. She’d been doing JavaScript for four and a half years, she rated her JavaScript skill as very good, and—as I found out soon after—she actually knew very little about JavaScript. I didn’t really blame her for that, though. JavaScript is funny that way. It’s the language a lot of people (including myself, until recently!)
