Difference between IIFE and call

Question

Is there a difference between:

(function(){

}).call(this);

and

(function(){

})();

or

var MODULE = {};
(function(){
    this.hello = 'world'
}).call(MODULE);

and

var MODULE = {};
(function(m){
    m.hello = 'world'
})(MODULE);

I often see the first case in compiled javascript. They both would create a scope and do their namespacing job well.

Is there any difference or is it just a matter of taste.

Edit: And why would compiled javascript would use call over IIFE?

Answer 1

(function(){

}).call(this);

calls the anonymous function where the this inside the function will point to the object referred by this when the call was made.

(function(){

})();

calls the anonymous function where the this inside the function will point to the global object (or undefined in strict mode)
