I’ll have to disagree with number 3, even so I learned Javascript before jQuery. I see where you are coming from here “learn the foundation and then move to a library”. If one learns jQuery, they will be saving a lot of time - and if one learn it and see it as a language, not as just a library, I’m sure they will be able to move to Javascript. Another point: when was the last time you used vanilla JS? I might be wrong, but I guess less and less people are using it.
