<body>    <p>count numbers:      <output id="result"></output>    </p>    <button onclick="startworker()">start worker</button>    <button onclick="stopworker()">stop worker</button>    <br />    <br />      <script>      var w;        function startworker() {        if (typeofworker) !== "undefined") {        if (typeof(w) == "undefined") {          w = new worker("demo_workers.js");          }        w.onmessage = function(event) {          document.getelementbyid("result").innerhtml = event.data;        };      } else {        document.getelementbyid("result").innerhtml = "sorry! no web worker support.";      }      }        function stopworker() {        w.terminate();        w = undefined;      }    </script>  </body>

i have been teaching myself html5 on w3schools website. while trying replicate web workers .js tutorial, keep getting errors in section saying: syntax error: unexpected token "!==" on 1 line , syntax error: unexpected token "else". can't seem find out why, i've compared code original on site , same. appreciated.

the problems second line of first function ( !== ) , else further down being flagged unexpected tokens.

var = 0;    function timedcount() {    = + 1;    postmessage(i);    settimeout("timedcount()", 500);    }    timedcount();

this .js html above.

i feel kind of stupid...just reviewed code , found missing parenthesis in first if statemeent of first function in html script. goes show taking break , coming review code can solve many problems.
