<html>
<head>
<meta charset="utf-8">
<title>Code Mirror</title>
<link rel="stylesheet" type="text/css" href="codemirror.css">
<script type="text/javascript" src="codemirror.js"></script>
</head>

<body>

    <textarea id='demotext'>

    function foo() {
        for(i = 0, i < 10, i++)
        console.log(i);
    }

    </textarea>

<script type="text/javascript">

    var editor = CodeMirror.fromTextArea(document.getElementById("demotext"), {
          lineNumbers: true,
          mode: "javascript"
    });

</script>
</body>
</html>

my code syntax inside textarea is not highlighting. CodeMirror syntax highlighting is not working here.

You need to load the mode for the language you want to highlight. In this case, load mode/javascript/javascript.js from the distribution.
