Simple jQuery method dependency loader

example.js

// simple script dependency delegation
// built specifically for backbone + jQuery
// loads scripts[] in parallel
var use = function(scripts, fn) {
  var complete = 0, 
  total = scripts.length,
  script;
  function done() {
    if(++complete === total && fn) fn();
  }
  return function() {
    while((script = scripts.shift())) {
      $.ajax({
        url: 'js/' + script,
        dataType: 'script',
        success: done,
        cache: true
      });
    }
  };
};

var form: {
  init: use(['jquery.validate.js', 'ajaxify.js'], function() {
    $('#form').ajaxify();
  });
}

// dependencies will be loaded in parallel once this is called
form.init();
