Looking through the list of functions and objects permitted for use (as laid out in the "Notes: Changed in MongoDB 2.4" box),
I can't find the reference material for any of the allowed functions in the map/reduce engine. For example, a search for assert() from the search box finds 133 items, none of which actually document the assert() function (at least, none of them start with the word "assert").
That's just the first of the 30 or so functions. Even "Map()" has the same problem. These mostly aren't "core javascript" functions; AFAICT, they all have dozens of implementations on the web, many with different calling sequences and behaviors.
Is there some place in the documentation that says which JS libraries this engine is built on, at least? It would be better, of course, if those function names were links.
