body: <p>As I know, writing a new line is "\n", so I tried many times but it wasn't working. This is my source code and screen shot of result </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>var ary3 = new Array('seven','eight', 'nine');
  for (var i =0; i&lt;ary3.length ; i++){
      document.getElementById('demo3').innerHTML += i+"'\nth element\n[enter image description here][1] : " + ary3[i]+"\n";
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;h1&gt;Show me the array object's entry&lt;/h1&gt;
  &lt;div id = 'demo3'&gt;&lt;/div&gt;
