I'm sure good documentation, i.e. one that starts at a basic level assuming almost no prior knowledge and then gradually building on that, would lower the barrier of entry for many autodidacts. Maybe that will be the norm one day. But until then, we all find ourselves in the position where we need to quickly scan a text in order to assess if the level expertise required to understand it is within our potential grasp or not. Especially the texts that are posted here. Sometimes one might go down a rabbit-hole, google all the terms and see if it fits in with one's already acquired body of knowledge in an adjacent field, and sometimes one might find that one's knowledge actually has expanded.

Admittedly, that is the good feeling of having learnt something new. But sometimes it's just too many new terms and concepts to learn. I don't fret about it, one can't know everything. If one tries I suspect it would be a shallow understanding - except for the odd genius maybe. But I doubt it, even then.

That said, you can't go wrong with learning Javascript (Typescript) these days. It's really not hard once you've got a grasp of the basics and there is all kinds of documentation that guides even the complete novice. Writing a web-site without JavaScript at all is commendable (especially here on HN), but it doesn't hurt to know how it works.
