Explanations are sparse
I prefer the term concise - no need to dredge through unnecessary waffle to figure out what something does.
> useful examples rare
Possibly. On most sites I tend towards going straight to the examples because the explanations are waffle, but don't need to with MDN.
> there's an assumption of underlying familiarity
That'll be because it's mostly a reference.
There is a JavaScript Guide which appears very comprehensive, but looking at a few pages it does a horrific job of explaining stuff and has some terrible examples, so, yeah... that sucks. :/
