FAQ Topic - What is (function(){ /*...*/ })() ?
-----------------------------------------------------------------------
This is an anonymous FunctionExpression that is called
immediately after creation.
Variables declared inside a function are not accessible from
outside the function. This can be useful, for example, to hide
implementation details or to avoid polluting the global scope.

a comment.
