javascript access class method without initializing object

Question

I have a class foo, can I access its public method bar with out initializing fooObj

var foo = function(){
   this.bar = function(){
       console.log("I am bar");
   }
}

I know I can access bar like

var fooObj = new foo();
fooObj.bar();

In other object oriented language like javeif I declare bar static I can access it with class name like foo.bar

Do not think in terms of "classes". Javascript doesn't have those. It's all just objects with properties. — deceze

There is no static concept like Java but you can do something like

var foo = function(){
   // Constructor specific code
}

foo.bar = function(){
    console.log("I am bar");
}

This is how singleton will be defined in JavaScript

If you add it to prototype, it should work when you instantiate an object and call the method present in it.

@ Vigneswaran Marimuthu I didn't get what I wanted as, deceze said Do not think in terms of "classes". Javascript doesn't have those. It's all just objects with properties.

@ozil What he meant is there is no concept of classes like in Java. If you see JavaScript you can see concepts like functions, objects and properties. Constructors are created using functions not classes in JavaScript. Though ES6 have classes concept but it's relatively new - javascriptplayground.com/blog/2014/07/…
