JSON

JSON parsing and stringification.

1. JSON.isRawJSON()

   JSON.isRawJSON() checks whether a value is a raw JSON object created by JSON.rawJSON(), helping avoid double serialization in data pipelines.

   JSON.isRawJSON(value)
2. JSON.parse()

   JSON.parse() converts a JSON string into a JavaScript value. Covers the reviver function, common errors, prototype pollution, and number precision handling.

   JSON.parse(text, reviver)
3. JSON.rawJSON()

   JSON.rawJSON() wraps a JSON primitive so JSON.stringify emits it verbatim. Use it for lossless 64-bit integers, exact unicode escapes, and tricky JS cases.

   JSON.rawJSON(string)
4. JSON.stringify()

   Use JSON.stringify() to convert JavaScript values to JSON strings, with replacer and space parameters for filtering properties and pretty-printing output.

   JSON.stringify(value, replacer, space)
