## Detailed Description

Data structure representing JSON format.

Limitation: UTF-8 is not properly supported. Code points above ASCII are invalid.

Examples:

// Create a JSON object.
Json object { Object() };
// Assign key "key" with a JSON string "Value";
object["key"] = String("Value");
// Assign key "arr" with a empty JSON Array;
object["arr"] = Array();
