title: VS Code - how to document an object using JSDoc
body: <p>I have a variable <em>storage</em>, that stores all elements of type <em>Person</em>. So basically it is a dictionary with key <em>URL</em> and value <em>PersonInstance</em>:</p>
  
  <pre class="lang-javascript prettyprint-override"><code>let storage = {}
  storage["localhost.com/person/1"] = new Person("John Wick");
  </code></pre>
  
  <p>Actually I could do it by writing:
  </p>
  
  <pre><code>/** 
   * @type {Object.&lt;string, Person&gt;}
   */
  </code></pre>
  
  <p>But VS Code Intellisense does not work in such case. Is there other way to document such object with unlimited number of keys in VS Code?</p>
