:content
Serializes either a `String` or a `DValue` into JSON notation.

When passed a `String`, `json_encode()` returns a quoted and escaped JSON string literal.

When passed a `DValue`, scalar values are serialized directly and nested map values are emitted as JSON objects.


:example
DValue value;
value["name"] = "Ada";
print(json_encode(value), "\n");
