C++ Singletons which don't leak
class Singleton {
public:
// Lazily get reference to a static instance of Singleton.
// The benifit of the following inplementation:
// * It lazily creates a Singleton.
// * It creates the Singleton on the global stack, so when the program ends
// the Singleton is automatically deallocated and it's deconstructor is invoked.
static Singleton& getInstance() {
// The following line (starting with `static`) only executes once,
// no matter how many times this function executes.

Shows how one could obfuscate the underlying details of some functionality in JS. Execute this in your browser to see what happens. I promise this is safe 😇

A brief overview of member initializer syntax in C++

C++ Member Initializer Syntax

Member initializer syntax is a great way to give data members initial values on object initialization.

"All other things being equal, your code will run faster if you use initialization lists rather than assignment." - isocpp.org

For the purposes of this example let's pretend we have the class Cat:

#include <iostream>
#include <string>
using namespace std;
