title: Class.prototype.method vs this.prototype.method
body: <p>I've always seen examples of Class.prototype.method, but never instances of this.prototype.method. For example:</p>
  
  <pre><code>function Class() {
      this.prototype.method = function() {
          alert("is this allowed?");
      };
  }
  </code></pre>
  
  <p>vs</p>
  
  <pre><code>function Class() {}
  Class.prototype.method = function() {
      alert("traditional example");
  };
  </code></pre>
  
  <ol>
  <li>Does this.prototype exist? </li>
  <li>Is it the same as Class.prototype? </li>
  <li>What about inheritance?</li>
  </ol>
