The short: Define and immediately execute an anonymous function.
The long:
function blah() { ... } // define a named function
blah(); // execute a named function
function() { ... } // define a function without a name (anonymous)
// can't execute the function because it doesn't have a name
A function is just another object in JavaScript. Functions have a
special "()" method / "operator" (to use a C++ term).
var temp = function() { ... }; // define and assign a function to a variable
temp(); // execute the function assigned to "temp"
The final ingredient: the extra ( ... ) around the function definition
isneeded because of a language syntax "quirk".
(function(){.....})(); // define and execute an anonymous function
Does that cover it?
