jquery fn vs commonjs

gistfile1.js

// non-modular
jQuery.fn.limit = function(count){
  return $(this).filter(function(index){ return index < count; });
};

// non-modular usage
$('sel').limit(3);

// modular
var $ = require('jquery');
var limit = function(count){
  return $(this).filter(function(index){ return index < count; });
};
module.exports = Function.call.bind(limit);

// modular usage
var limit = require('./plugins/limit');
limit($('sel'), 3);
