Awkward way of executing JavaScript code
javascript
Solution
This is a poor example. Consider the following:
var a = (function() {
var ret = {};
ret.test = "123";
function imPrivate() { /* ... */ }
ret.public = function() {
imPrivate();
}
return ret;
})();
console.log(a)
`a` will contain the varible test and the function public, however you can not access imPrivate. This is the common way to handle public vs private variables;

Problem
In the Google tutorial for implementing Google+ sign-in in Flask application, I discovered that the developer often uses an awkward way of executing JavaScript code: Instead of doing ``` var a = foo(bar); ``` I see this: ``` var a = (function() { return foo(bar); })(); ``` What is the reason to do it the weird way?
