module pattern

var Module = function(){
  var privateProperty = 'foo';
  function privateMethod(args){
    // do something
  };

// example car

var Car = function(){
  var gasolineLevel = 10;
  
  function useGas(amt){

     console.log("no more gase")
    } else {

  radiotStation: "104",

  },
  go: function(speed){ useGas(speed); }
 }
};

var honda = Car();
honda.go(2);
honda.go(10);
