JSON type representation

JSON is a convenient and widely used format for serializing objects, arrays, numbers, strings, booleans, and null. JSON does not support all data types allowed by JavaScript, which means that JavaScript objects that use these incompatible types cannot be directly serialized to JSON.

The JSON type representation of a JSON-incompatible object is an equivalent JavaScript object with properties encoded such that the information can be serialized to JSON. This typically has the same properties as the original object for compatible data types, while incompatible properties are converted/serialized to compatible types. For example, buffer properties in the original object might be base64url-encoded to strings in the JSON-type representation.
