/// @assertion String convert(Object o)
/// If the conversion throws, or returns a value that is not directly
/// serializable, a JsonUnsupportedObjectError exception is thrown. If the call
/// throws, the error is caught and stored in the JsonUnsupportedObjectError's
/// cause field.

/// If a List or Map contains a reference to itself, directly or through other
/// lists or maps, it cannot be serialized and a JsonCyclicError is thrown.

/// Json Objects should not change during serialization.
/// If an object is serialized more than once, stringify is allowed to cache the
/// JSON text for it. I.e., if an object changes after it is first serialized,
/// the new values may or may not be reflected in the result.
 
/// @description Checks that if the object does not support "toJson()" method,
/// then an exception is thrown
