Why drop jQuery now?
When I was a beginner, I became very good in HTML & CSS and could use jQuery. Some jQuery plugins here and there, but it was just only implementing the examples, change the selectors and it was done. But when I had a bug like jQuery is undefined, I could not fix it, because I didn’t exactly understand what was happening.
