JSON.stringify II

Requirements

• Export stringify as named and default. Implement compact serialization without JSON.stringify or serialization libraries.
• Escape quotes, backslashes, control characters, and lone UTF-16 surrogates; preserve valid Unicode pairs. Serialize nonfinite numbers as null and -0 as 0.
• Visit own enumerable string keys in Object.keys order. Ignore inherited and symbol keys, and custom array properties. Do not mutate input.
• Return undefined for top-level undefined, functions, and symbols. Omit them in objects, and replace them with null in arrays including sparse slots.
• Call callable toJSON on objects before serialization, with its own this and property key (empty string for root, string index for arrays). Do not invoke toJSON again on its replacement at the same position.
• Unbox Number, String, and Boolean objects. Support Date through toJSON. Map, Set, and symbol wrappers behave as enumerable objects.
• Throw TypeError for encountered BigInt or active ancestor cycles. Allow repeated references that are not cycles.
• Replacer, indentation, rawJSON, boxed BigInt, cross-realm wrappers, proxies, and hostile getters are excluded.

Examples

Input: stringify({ missing: undefined, values: [undefined, NaN] });
Output: {"values":[null,null]}
