Question

I understand how to call a callback normally, but when I try to call a callback using the arguments array it doesn’t work. Here is code for how it is normally:

function someFunc(parameter1, callback){
  alert(parameter1);
  callback.call();
}

someFunc('Hello', function(){
  alert('World!');
});

And the exact same format using the arguments array, which doesn’t work.

function someFunc(parameter1){
  alert(parameter1);
  arguments[arguments.length-1].call();
}

someFunc('Hello', function(){
  alert('World!');
});

What is going on here?

Your code has no errors whatsoever and should work fine on its own. This example shows that it is working perfectly. — http://jsfiddle.net/FDT8N/
