Transition from front-end to back-end?

Question

PHP

Hello everyone, the situation is this, I work as a junior front-end, I like the work, everything suits me, but I often see that all backenders work normally with the front to one degree or another, like a medium layout, or, for example, deploy the front on vuejs / angularjs, unless that they won’t deal with angular with a swoop, it will take time. As a result, everything is good, but internally I start to feel like a kind of software invalid, that I can only create the client part of the application, and backenders can fully deploy it, in the end I think that it’s better to switch to back or full stack, but again, full stack is too much dispersion.
The question is purely philosophical - to develop comprehensively or, on the contrary, to delve into a specific area, I would like to hear the opinion of experienced authoritative people.
Sorry it's confusingly written.

Answer 1

Well, no one will make the decision for you, but it would be nice for the front-end developer to know how the back-end works and vice versa. I think that 1 programming language php or python will not become a strong spray. But you will be able to communicate better, set tasks, ask questions.
As a backender, I am also not going to deeply understand the front, but I consider it necessary to launch a simple SPA on React or Vue, so I will dig in this direction. You just immediately determine for yourself this transition or acquaintance))

Answer 2

So there is Node.js and spraying will be minimal. And async/await out of the box)
