json-stable-stringify-without-jsonify deterministically stringifies JavaScript objects into JSON, ensuring consistent output regardless of key order. Unlike standard JSON stringifiers, this package avoids using JSON.stringify directly, offering environments without it (like sandboxes) a reliable alternative. It guarantees stable key ordering for predictable JSON outputs, which is vital for applications requiring consistent hashing or comparison of JSON data, especially in cryptographic or data integrity contexts. Its primary function is to provide stable and predictable serialization.
