Jun's tech stack?

Question

JavaScript

Hello everyone. The question is hackneyed and there are about a billion answers to it, but they are all different and the companies have different requirements. Therefore, I will ask again to be sure.
It means that I am actively studying Java and JS. I know Java at the level of understanding the whole book of Hortsman and other suitable literary products.
Also at a good level are HTML / CSS and SASS / LESS preprocessors. From the bootstrap and materialize frameworks (not the best choice, as I know, but it came to me). There are projects of their own landing pages, written both on frameworks, and completely with their own code (media queries, adaptability, everything is present).
There are no projects written by me in Java, Spring and Hibernate are in the process of studying, and I heard about Tomcat and Maven very remotely.
What technologies could you, dear, advise me for learning, in addition to bringing all of the above to automaticity?
I threw an invite to a local IT company in my backwoods - they rejected it, because there is no tower directly related to programming, although they liked my technology stack (well, or they didn’t want to offend me).
According to information from acquaintances in all mini-towns of the Republic of Belarus, they will demand higher education from me, so for now only Minsk is the only option. They don’t seem to look at it, but, accordingly, they will demand more.
PS I will be grateful to any suitable free (poor student) sources for studying certain technologies.
PPS Thanks for the answers, which I hope will be.

Answer 1

1) Java is a corporate stack, so we stomp to a local company where they write in Java. We talk, we ask. They will tell you themselves what they write on and what they need as a minimum.
2) The Java problem is that you yourself at home, on your projects, can’t practice at all, because your projects and corporate legacy monsters are like heaven and earth, they have nothing in common. Therefore, it is only in practice or internship that you need to fill bumps.

Answer 2

Not strong in Java, but I can say about js. At the moment, in this direction, the technology stack is something like this: Jquery (despite the fact that it is slowly dying), React, Vue, if you delve into the backend, you will definitely need to feel NodeJs, NoSql and Sql DB, and there it will most likely come, something like PHP and a new stack will be defined, if more to the front, then CSS preprocessors are better, SASS is better, since LESS is already dead enough not to bother with it, and HTML5. In general, everything is quite ambiguous because the IT industry is very dynamic. Therefore, you just need to start with something, and then the stack will be pulled up in the process.
