Is Vanilla JavaScript worth learning? Absolutely.
David Kopal

Great! This article really confirms my determination to study the vanilla JavaScript and computer basics as my major is not computer science related neither. Recently I am studying algorithm and found it quite interesting and can help me practice my programming thinking. And for JS frameworks, I have the same idea that you don’t need to learn all of them, once you get to know the core of JavaScript, they are just syntaxes. Just learn them when they are needed.

I would carefully read the articles you recommend! Thank you so much.
