There is wisdom in this comment. It's important to note, though, that the point about investment applies also to the tools and methodology that the blank slate programmers are being steered towards.

It's both interesting and exasperating that the modern JS ecosystem and its influencers have managed to recreate the experience of downloading SDKs and fiddling with configuration options and dealing with builds that sometimes fail, and that when they don't, build success means producing inscrutable blobs where View Source is rendered useless. On the whole, it's a community that has neglected to maintain the ecosystem's original strengths.

But OP isn't a newbie going to coding school, he/she already knows JavaScript and webdev in general ! Of course if you don't know programming at all it's harder (even then, 3 months seems like an awful lot - this year I teach programming to graphic design students and in ~15 hours they are already able to do neat things on their own with p5.js).

To give my own experience, I'm almost exclusively a C++ coder but had to do two Web projects earlier this year, a React one and a custom one, and even though both times it felt like eating nails, it didn't take more than a day to "get in" ; I'm confident that it's be the same no matter the language except maybe APL and derivatives :)
