This site is IMO the best reference out there for modern JS/DOM fundamentals. It's concise, clear, consistent, accurate, and well-organized throughout, which is no mean feat for how many topics it covers.
It swaps to an ironic, sarcastic, in-jokey tone almost completely divorced from the previous sections that will leave much of the intended audience (people new-ish to programming) utterly confused by what is being said—or in this case, worse, what is intentionally not said. The effect of this self-absorbed style of teaching is so poor, I think, that that page actually damages the overall text in its current state.
Surely the point of a site like this shouldn't be shaped for the entertainment of experienced programmers, but to help less experienced programmers know what to do—and what not to do. They could still make it funny, just... not that.
