Singleton Pattern in ES6: The Good, The Bad, The Ugly

Too Long; Didn't Read

Singleton Pattern in ES6: The Good, The Bad, The Ugly. A singleton is a class that allows only a single instance of itself to be created and gives access to that created instance. It only instantiates a singleton once, and therefore any code that accesses the singleton will either create a new instance or modify that instance. Singletons are dangerously close to being a global variable, and we don't like those. Redux, vuex, singletons and globals all suck to varying degrees.
