title: combining strings and returning - javascript
body: <pre><code>&lt;html&gt;
  &lt;script type = "text/javascript"&gt;
      function concatStrings(){
        var string1 = "programming";
        var string2 = "class";
        var sentence = string1 + " " + string2;
        return sentence
      } 
  &lt;/script&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I am new to JavaScript and was wondering how to get a simple statement to return. I tried this and tested it but nothing had shown up. What should I do to have the variable, sentence, to show up?</p>
