mongo-eql

mongo-eql (v1.0.0) implements MongoDB-style equality comparison for JavaScript data structures. It evaluates values using the same semantics as MongoDB's $eq operator, treating null and undefined as equal and performing deep equality on objects. The package is minimal, with no dependencies, and targets Node.js or browser environments. It is stable but no longer actively maintained (last release 2015), and offers a focused alternative to lodash.isEqual or deep-equal for MongoDB-like behavior.
