Sometimes we need to hide the JavaScript code from the old browsers that do not support it.

To prevent old browsers from displaying your JS code, do the following:

 

Immediately after the opening <script> tag, put a one-line HTML-style comment without the closing characters, so that the first two lines of your script would look like this:

<script language="JavaScript">
<!--
 
At the end of your script, put the following two lines:
//-->
</script>
 

Thus, your HTML file will contain the following fragment:

<script language="JavaScript">
<!--

    Put your JS code here. Old

    browsers will treat it as regular

    HTML comment.
//-->
</script>

 

 

Old browsers will treat your JavaScript code as one long HTML comment. On the other hand, new JavaScript-aware browsers will normally interpret the code between the tags <script> and </script> (the first and last lines of the code will be treated by the JavaScript interpreter as one-line comments).
