What is the difference between these 2 JavaScript declarations?

Question

For one of them the \"()\" is inside, for the other one it is outside. Here they are:

var a = (function() {
    return {
        bla: function(         


        

Answer 1

I think is the same difference of this:

var myObj = {bla:'blabla'}; 
var a = (myObj);
var b = myObj;

...no difference :)
