IIFE invocation in JavaScript

by

That depends on where the code is executed.

.call(this) explicitly sets the this to the object you pass to .call. Only using (); will set this to window (or to undefined in strict mode).

If the code is executed in global scope it will be the same. If not, then you will get different results if this does not refer to window (or is undefined).

Example:

var obj = {
   foo: function() {
       (function(){
           console.log(this); // this === obj
       }).call(this); // this === obj

       (function(){
           console.log(this); // this === window
       })();
   }
};

obj.foo();
