Should You Learn Ruby On Rails Today?

Question

Ruby on Rails

I want to learn Ruby on Rails, partly for my own needs, partly for a job advantage as a front-end developer, but I'm not sure if I made the right choice.
Is Ruby On Rails Worth It Today? Or has the fashion for it already irrevocably passed?
Will the knowledge and understanding of the Ruby-on-Rails project work in the next couple of years? Or is it better to explore some more fashionable alternative? What?
Is it rational to use Ruby on Rails for your self-written home startup?

Answer 1

Is Ruby On Rails Worth It Today?

Costs.
The peak seems to have passed.
If he wants to write full stack.
Depends on the project.
PS Ruby on rails, like ruby, is just a tool. Yes, it's cool and handy, but it's just a tool. If you know how to solve problems, then it will not be difficult to master another tool when you need it.

Answer 2

Fashion comes and goes, whatever. Someday, all these nodes and reacts will become a thing of the past and will seem like old farts. Therefore, focusing on fashion is not worth it.
"Will the knowledge and understanding of the work of the project on Ruby on Rails be useful to the front-end developer in the next couple of years?" - it all depends on the projects in which you will work. If Rails and Sprockets are used there, then yes, the front-end developer needs to understand. If the frontend is assembled there separately on gulp / grunt / something else, then the front-end developers there will not contact Rails, so they don’t really need to know them.
If there is a SPA, then the front-ender does not care at all what is on the back-end.
"Is it rational to use Ruby on Rails for your self-written home startup?" — if you know Rails, then yes.
