I declare a string of HTML and set it equal to a variable. I can’t think of any reason it would generate an error, yet here it is:

Uncaught SyntaxError: Unexpected identifier on Ln 136.

Ln 136: new_comment = '
    <li class="photobooth-comment">
       <span class="username">
          <a href="#">You</a>
       </span>
       <span class="comment-text">
          ' + text + '
       </span>
       <span class="comment-time">
          2d
       </span>
    </li>
';

    If you want to include line breaks in your actual code to make it easier to read, you’re going to need to escape each one with a backslash, e.g.:

    var new_comment = '\
    <li class="photobooth-comment">\
       <span class="username">\
          <a href="#">You</a>\
       </span>\
       <span class="comment-text">\
          ' + text + '\
       </span>\
       <span class="comment-time">\
          2d\
       </span>\
    </li>\
';

    Or you’re going to need to concatenate them as individual strings, like so:

    var new_comment = ''+
    '<li class="photobooth-comment">' +
       '<span class="username">' +
          '<a href="#">You</a>' +
       '</span>' +
       '<span class="comment-text">' +
          text +
       '</span>' +
       '<span class="comment-time">' +
          '2d' +
       '</span>' +
    '</li>'+
'';

    Or simply put it all on one line:

    var new_comment = '<li class="photobooth-comment"><span class="username"><a href="#">You</a></span><span class="comment-text">' + text + '</span><span class="comment-time">2d</span></li>';

    Not so easy to read but neater for your JavaScript!
