First you may have noticed that we've created all objects on the stack. You are of course also free to create them on the heap with the C++ operator 'new'. That works just as well, and is in real life code probably more useful as you normally want to keep your handlers, connection...
A non-placement deallocation function for a class is odr-used by the definition of the destructor of that class, or by being selected by the lookup at the point of definition of a virtual destructor. An assignment operator in a classTthat is a member or base of another classUis odr-used...
There are myriads of JSON libraries out there, and each may even have its reason to exist. Our class had these design goals: Intuitive syntax. In languages such as Python, JSON feels like a first-class data type. We used all the operator magic of modern C++ to achieve the same feeling...
Polymorphism means the ability to take more than one form.An operation may exhibit different instance. The behaviour depends upon the type of data used in the operation. A language feature that allows a function or operator to be given more than one definition.The types of the arguments with ...

A function that is explicitly defaulted must be a special member function or comparison operator function(since C++20), and it must have no default argument. An explicitly defaulted special member function F1 is allowed to differ from the corresponding special member function F2 that would have ...
