Detailed Description

example deserialize:

Json obj;
obj.deserialize("{\"a\":5}");
std::cout << obj["a"].isNumber() << "\n"; // 1
std::cout << obj["a"].number() << "\n"; // 5

example number:

Json obj;
obj["a"] = 5;
obj["b"] = 3.14;
std::cout << obj.serialize(0) << "\n"; // {"a":5,"b":3.14}

example string:

Json obj;
obj["name"] = "John";
 
std::cout << obj["name"].isString() << "\n"; // 1
std::cout << obj["name"].string() << "\n"; // John
std::cout << obj.serialize(0) << "\n"; // {"name":"John"}

example array:

Json obj;
obj["dim"][0] = 10;
obj["dim"][1] = 20;
obj["scale"] = std::vector<double>{ 1, 2, 3 };
 
std::cout << obj.isObject() << "\n"; // 1
std::cout << obj["dim"].isArray() << "\n"; // 1
std::cout << obj["dim"].size() << "\n"; // 2
std::cout << obj["dim"][0].number() << "\n"; // 10
std::cout << obj["dim"][1].number() << "\n"; // 20
 
double area = 1.;
for (auto const &it : obj["dim"].array())
{
    area *= it.number();
}
std::cout << area << "\n"; // 200
 
std::cout << obj.serialize(0) << "\n"; // {"dim":[10,20],"scale":[1,2,3]}
