    Cryptographic operations like hashing and signing requires that the
    original data does not change during serialization or parsing.  One
    way addressing this issue is creating a canonical form of the data.
    The JSON Canonicalization Scheme (JCS) performs this task on data
    provided in JSON [RFC8259] format.  JCS achieves this by building
    on the strict serialization formats for JSON primitives defined by
    ECMAScript [ES6], constraining JSON data to the I-JSON [RFC7493]
    subset, and through a platform independent property sorting scheme.


Better?
