title: String join with newline in an array in Coffeescript/Javascript
body: <p>I'm currently using the Instagram API to retrieve a user post's caption as well as their hashtags. I'm mapping each post but I'm having trouble joining the array with newline; also, I want to add a hashtag symbol before each hashtag. I know this sounds confusing, but I'll demonstrate with code snippet and screenshot:</p>

  <p>This is the photo object that I have access to. If you look under "tags", there are four hashtags that I want to display. All four of them are displaying, but in the same line, and only the beginning line gets the hashtag.</p>
  
  <pre><code>eachPost: (post) -&gt;
    return (
      &lt;tr&gt;
        &lt;td&gt;#{post.tags.join("\r\n")}&lt;/td&gt;
      &lt;/tr&gt;
    )
  
  render: () -&gt;
    return (
      &lt;table&gt;
        &lt;tbody&gt;
          &lt;tr&gt;
            &lt;th&gt;Hashtags&lt;/th&gt;
          &lt;/tr&gt;
          {_.chain(@state.posts.data).map(@eachPost).value()}
        &lt;/tbody&gt;
      &lt;/table&gt;
    )
  </code></pre>
  
  <p>This is what's showing up. The left column is Caption, and right column is Hashtags:</p>
