JQuery Update Old Version to New Version

Hi Surender,

I have upgraded jQuery (from v1.8 to v3.6) recently in a few of the projects due to some security vulnerabilities reported by the Security Team, The best way to upgrade it is to use https://github.com/jquery/jquery-migrate (jQuery Migrate Library) and keep an eye on the console for the errors or warnings.

jQuery, on their official website, provides the upgrade guide which you can also refer to in case you find some breaking changes.

I hope this will help you.
