There isn't really a name for that entire thing. It's an anonymous function
that is defined and called immediately.
The purpose of it is to provide a local scope for variables and functions.
Let's break it down:
function(){/*code*/} is an anonymous function.
You call a function by putting () after it, of course. But this is a syntax
error for obscure reasons:
function(){/*code*/}();
However, throw some parentheses around the anonymous function:
(function(){/*code*/})
and now you have something that you can call by adding parens afterward:
(function(){/*code*/})();
By creating and calling a function, any "var" statements or function
definitions inside that function are local to the function.
