A very easy javascript inheritance pattern. I use it for my node.js projects and I love it

pattern.js

module.exports = function () {
    var self = {};

    self.run = function () {
      console.log("Hello I'm a method");
    };

    return self;
};
/*
 * We can now construct this using:
 * var pattern = require("./path/pattern.js");
 * pattern().run();
 */
