Is there a difference/benefit between these two ways of instantiating an object?

Example:

var Person = (function () {
 function Person() {
 }
 return Person;
})();

var p = new Person();
p.Name = "Greg";
window.console.log(p.Name);

var x = new Person;
x.Name = "Pete";
window.console.log(x.Name);

Not really. See http://stackoverflow.com/questions/3034941/new-myobject-vs-new-myobject for explanation. – Etzeitet Feb 18 '14 at 21:03

therefore it's a duplicate – Roko C. Buljan Feb 18 '14 at 21:03

If a constructor takes no arguments, the empty parenthesized argument list is optional when the constructor is invoked with `new`. – Pointy Feb 18 '14 at 21:03
