I work for a famous Silicon Valley company and we use Ruby, Python, Swift, C++, Obj. C primarily. JavaScript is used by front-end types, but at least around here, JavaScript isn’t really a serious language outside of front end development. It’s certainly not being used for server-side anything or at least not on any project I know about. However there are some serious systems (hundreds of millions of user accounts) that actually use rails. There is a lot of python here but not much Django. A bit of Java in some systems, but the “cool” stuff is Swift, Objective C, Ruby, C++.
The Ruby community is just as vibrant as is always has been but it’s a little less infected with hipster trend chasing than it used to be. JavaScript is the clear winner in that regard. JavaScript is also a noisy community in that there is a lot of ways to skin a cat, while the Ruby world tends to be more opinionated. So, in my opinion, the Ruby (and Rails) Way is a “thing,” while there really isn’t a cohesive “JavaScript Way.”
If I were starting over from zero, I’d still learn Ruby and Rails, but I’d probably lean towards Swift and Vapor. Vapor feels like the Rails community circa 2010 and Swift is blazing fast and can be used for native Mac/iOS, web applications, and highly performant server applications.
To be clear, I am not suggesting not learning JavaScript, but I personally wouldn’t make it my primary language. But I kind of follow my own trail, so my advice might not be popular, however it has worked for me.
