In MongoDB, you can use JSON-style objects such as in the following to query a collection:

db.things.find({ x : { $ne : 3 }, y : \'foo\' });

I dont think you can just use the mongodb filters in normal js arrays. Because you need to understand the fact that

The filters specified in mongodb are evaluated in mongodb indexes not in the javascript result set

Means the filters evaluated(translated) to query against a index not the js. So what you are asking is a DSL on top of mongodb(or JS) which will evaluate the mongodb index filters in the JS array.

I dont think its needed since both serves the different purposes (Though its possible(difficult) to write custom DSL). Also there are major frameworks like underscore.js already provide a ways to handle these.
