  1. How can JavaScript codes be hidden from old browsers that don't support JavaScript?

    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.
