Answer:

For hiding JavaScript codes from old browsers:

Add "<!-" without the quotes in the code just after the <script> tag.

Add "//->" without the quotes in the code just before the <script> tag.

Old browsers will now treat this JavaScript code as a long HTML comment. While, a browser that supports JavaScript, will take the "<!-" and "//->" as one-line comments.
