title: jQuery datepicker not displaying after trying to change the language
body: <p>I am completely new to jQuery.</p>
  <p>I am trying to use jQuery datepicker for my HTML form. In the English language datepicker displaying as it should. But when I tried to change the language to slovak according to tutorials on the web, datepicker stop displaying and I don't know why at this point. Maybe I am missing something easy, but I looking for answers for 2 hours now and nothing seems to work.
  Here is my code:</p>
  <p>Head:</p>
  <pre class="lang-html prettyprint-override"><code>    &lt;script src='jquery-3.2.1.min.js' type='text/javascript'&gt;&lt;/script&gt;
      &lt;link href='jquery-ui.min.css' rel='stylesheet' type='text/css'&gt;
      &lt;script src='jquery-ui.min.js' type='text/javascript'&gt;&lt;/script&gt;
      &lt;script src='datepicker-sk.js' type='text/javascript'&gt;&lt;/script&gt;
  </code></pre>
  <p>HTML:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;input type='text' id='datepicker' &gt;&lt;br/&gt;
  </code></pre>
  <p>JS:</p>
  <pre class="lang-js prettyprint-override"><code>$(function ($) {
      $(&quot;#datepicker&quot;).datepicker(
         {
            language: &quot;sk&quot;,
            format: &quot;dd.mm.yyyy&quot;,
            startDate: new Date()
         });
  });
  </code></pre>
  <p>This renders a text field, but no jQuery calendar in the Slovak language.</p>
