Converting an array to a list using javascript

Question

There are several methods that return arrays, which we all know express cannot handle. The IDM faq metions you can use a script tag to manipulate array data, but gives no example. I like this method because some methods I encounter preface the object name with the object type, and the data needs to be cleaned before use. I always like little snippits that can be reused, so I'm sharing this one.
Here is how to convert an array to a list, assuming the array is captured in "stupidarray":
    <split>
      <script>
        var myarray = env.get('stupidarray');
        // Code to manipulate the array
        outputarray = myarray.join(",")
        // Other code to manipulate the string before output
        // i.e. Stripping out the object type tags!
        // outputarray.replace(/User:/g,"");
      </script>
      <s>,</s>
    </split>
