Attitudes have changed since 2016. The verbatim tag is disabled (because of the security loophole mentioned in the thread), Mediawiki namespace access is restricted and the increased use of mobiles means using js on content is discouraged.

Other people here will tell you I know sweet Fanny about JS, so I'm no help there. I would only recommend looking for alternative means to present your data. For more specific help, I would recommend going to the Dev wiki and their Discord server.
