What will be if you set the anonymous function as value of variable

Just imagine, or type in console:

let test = function (){}; 
let t = new test(); 
console.log(t.constructor); //ƒ () {} 

function Test(){}; 
let T = new Test(); 
console.log(T.constructor); //ƒ Test () {}

So, if you want to write code in OOP style, I think, it will be better not to use anonymous functions.

singletone

var Singletone = (function () {
	var instance;

	return function Construct_singletone () {
		if (instance) {
			return instance;
		}
		if (this && this.constructor === Construct_singletone) {
			instance = this;
		} else {
			return new Construct_singletone();
		}
	}
}());
