// Immediate execution with one parameter...
(function(param){
    alert ('Function 1: ' +  param);
})(11);

// Immediate execution with one parameter, within an Immediate execution...
(function(param){
    alert ('Function 2: ' + param);
}(22));

// Block with two Immediately executed functions
(
    function(param){
        alert ('Function 3: ' + param);
    }(33),
    function(param){
        alert ('Function 4: ' + param);
    }(33)
);

// Block with two, the second function will be executed immediately
(
    function(param){ // this function will never be executed
        alert ('Function 5: ' + param);

    },
    privateParam = 200, // this parameter can be used since here...
    function(param){
        alert ('Function 6: ' + (param + privateParam));
    }
)(44);

// Defining and executing the function immediately after...
var Foo = 1 + function(){
    return 55;
}();
alert ('Function 7: ' + Foo);

// Defining and executing the function immediately after with a parameter...
var Boo = function(param){
    return 'Function 8: ' + (1 + param);
}(66);
alert (Boo);
