title: How to change value of the object's property
body: <p>I have problem with understanding one aspect.</p>
  
  <pre><code>var Car = function(name, loc) {
      'use strict';
      this.name = name;
      this.loc = loc;
      this.methods = {
          move: function() {
             this.loc++;
          },
          show: function() {      
              console.log('Position of ' + this.name + ' is: ' + this.loc);
          }
      };
  };
  var amy = new Car('amy', 1);
  var ben = new Car('ben', 9);
  </code></pre>
  
  <p>When I use this.loc++ it's referring to methods object, not to Car object. And location of car is not incremented. My question is how to jump to car object context from methods?</p>
