It is the function itself. It was put in to the language to make
recursion of an anonymous function possible.
function fib(n) {
if(n==0) return 0;
if(n==1) return 1;
return fib(n-2) + fib(n-1);
}
is the same as
function fib2(n) {
if(n==0) return 0;
if(n==1) return 1;
return arguments.callee(n-2) + arguments.callee(n-1);
}
The example code could be revised to not need arguments.callee:
var scripts = [
'js/ui.core.js',
'js/ui.dialog.js',
'js/ui.tabs.js',
'js/ui.datepicker.js',
'js/ui.resizable.js',
'js/ui.accordion.js'],
n = 0;
function load_handler(){
if (scripts[n]) {
$.getScript(scripts[n++], load_handler);
} else {
$('#foo1').dialog({...});
$('#foo2').tabs({});
$('#date1').datepicker({...});
$('#foo3').resizable({...});
$('#foo4').accordion({...});
}
}
$.getScript(scripts[n++], load_handler);
