Hey, Stephen, yeah, I received a few similar comments, but I think the questions, as they are, are appropriate to the article, which is talking about the state of web developers in today’s market: if you know the answer, you probably agree with him; if you don’t, then you probably should attend one of his courses… :-) Or, like me, be inspired to dig deeper and make myself a better developer. I went hunting for resources to buff-up on these bits, and landed myself on Addy Osmani’s Essential JS Design Patterns Book. From there, I will hunt for something else in a similar, advanced direction…
