Callback function example

callback.js

function callCallbackFunction (callback) {
  callback(); // all this does is call the function that is passed in as a parameter
};

callCallbackFunction(function(){ 
  alert('this is inside the callback function'); 
});


// Here is another way to do basically the same thing

var myFunction = function() { 
                  alert('this is another way to call the function') 
                 };

callCallbackFunction(myFunction);
