json
native moduleJSON parse/serialize. import "json". Objects ↔ maps, arrays ↔ lists, numbers → int (no ./e) or float, true/false → bool. JSON null decodes to nil (Zinc's nil is a real, writable value).
json.parse(s: string) => (any, string?)json.stringify(value: any, indent: int?) => (string, string?)
json.parse(s: string) => (any, string?)
Parse a JSON document. (nil, "invalid JSON") on malformed input.
json.stringify(value: any, indent: int?) => (string, string?)
Serialize to JSON; indent spaces per level (default 0 = compact). nil → null. Errs if the value contains a non-finite float (NaN/Infinity), an unrepresentable kind (struct instance, closure, enum value, def, module, iterator) — JSON cannot represent any of these — or if two map entries would render to the same JSON key (e.g. int key 1 and string key "1"), which would silently clobber one entry.
