The thing that strikes me, as an outsider, about the JS community is that most of their arguments and discussions tend to revolve around specific tools or libraries (Knockout vs. Backbone, for example), rather than around concepts.

As a result, many of the JS devs that I have worked with are good at using these tools, but are often deficient in knowledge of general good software development techniques. This includes testing, writing readable and maintainable code, design patterns, architectural principles, etc.

I guess that's what happens when you have a community where a substantial part believe JavaScript is 'close to the metal'

Do they really ? And why the heck would they believe that ?

I thought the article was just going to be two words: "associative arrays".

Instead it was about scene garbage that self-described "ninjas" blather about.
