title: what's the typeof(jQuery)
body: <p>i just tried this code</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>console.log(typeof(jQuery))</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.1/jquery.min.js"&gt;&lt;/script&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>It alerts <code>function</code>, which means the <code>typeof</code> jQuery is <code>function</code>.</p>
  
  <p>My question is, what's the exact type of jQuery? If it's function, how come it has properties like <code>jQuery.browser</code> and <code>jQuery.ajax</code>?</p>
