Function - SimplestCleanest way to implement singleton in JavaScript

Questions

What is the simplest/cleanest way to implement singleton pattern in JavaScript?

Answers

I think the easiest way is to declare a simple object literal:

var myInstance = {
  method1: function () {
    // ...
  },
  method2: function () {
    // ...
  }
};

If you want private members on your singleton instance, you can do something like this:

var myInstance = (function() {
  var privateVar =   ;

  function privateMethod () {
    // ...
  }

  return { // public interface
    publicMethod1: function () {
      // all private members are accesible here
    },
    publicMethod2: function () {
    }
  };
})();
