In addition to the other answers you've gotten (which are right), I think the real answer is JSON. I mean, JSON stands for "JavaScript Object Notation" (I think), but it means that your query results are effectively mapped to objects immediately.
Mongo especially returns JSON as its results, so it's usually the first choice for JS-based frameworks, for better or worse.
