title: Immutable.js - toJS Is Not A Function
body: <p>I am getting the typeError when I try using this function.</p>
  
  <p>As per the <a href="https://facebook.github.io/immutable-js/docs/#/Map/toJS" rel="noreferrer">Immutable.js</a> docs, I want to convert an obj into normal JS obj.</p>
  
  <p>Here is the example:</p>
  
  <pre><code>import { Map as iMap,
           toJS } from "immutable";
  
      let anExample = iMap({
          a : "a",
          b : "b"
      });
      console.log( "anExample is...", toJS( anExample ) );
  </code></pre>
  
  <p>I do not get an error on <code>Map</code>, but I do on <code>toJS</code>. What am I doing wrong?
  Thanks,</p>
