Is there a way to use MongoDB query objects to filter regular JavaScript arrays?

Question

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\' });

Ok, so here's another try:

sift.js (npm: sift) by Craig Condon is a MongoDB-inspired array filtering library. It’s a bit like an alternative to Underscore for people who love MongoDB. Sift.js supports operators like $in and $gt, but can also filter arrays based on functions and even works with deeply-nested objects in arrays.

Craig has provided a few examples that should look familiar to Mongo users:

var sift = require('sift');

sift({ $in: ['hello','world'] }, ['hello','sifted','array!']); //
['hello']
