Ask HN: Is there a best practices for jQuery in 2020?

I'm writing a basic front-end for a Django app. I just need a liiitttle js to smooth things UX-wise. I don't know any JS frameworks and I'm not vanilla JS savvy.

Having used jQuery in the past, I think it would be fine for my use case. However, I don't want to end up with a mess on the front-end.

How do I write jQuery that doesn't end up that way? Is there a canonical text or set of best practices I can follow?
