JRuby vs Ruby: What are the differences?
Developers describe JRuby as "A high performance, stable, fully threaded Java implementation of the Ruby programming language". JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java. The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information. On the other hand, Ruby is detailed as "A dynamic, interpreted, open source programming language with a focus on simplicity and productivity". Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.
JRuby and Ruby belong to "Languages" category of the tech stack.
"Java" is the top reason why over 7 developers like JRuby, while over 590 developers mention "Programme friendly" as the leading cause for choosing Ruby.
JRuby and Ruby are both open source tools. It seems that Ruby with 15.9K GitHub stars and 4.25K forks on GitHub has more adoption than JRuby with 3.32K GitHub stars and 830 GitHub forks.
According to the StackShare community, Ruby has a broader approval, being mentioned in 2530 company stacks & 1140 developers stacks; compared to JRuby, which is listed in 13 company stacks and 4 developer stacks.

I started with a CodeAcademy course before working on my first Rails project. The language is easy to read and Rails is an amazing framework. The online community is fantastic, the documentation is amazing, and there is no shortage of Ruby Gems which allows you to quickly "cobble" together a new project.
Only thing worth noting here is that we saw some major issues with memory swapping on Heroku with Ruby 2.1.2. We weren’t the only ones. So we actually reverted back to 2.0.0. Here’s what happened: . We’re planning to upgrade to 2.1.4 once we’ve had time to test thoroughly.
When we are comparing Turing complete languages it's not about what compiles faster or to the cleanest machine code, it's about what the developer can think in and write faster, including the availability of libraries. A couple of times I wrote some ruby scripts for this project. I just like the language best for some things. Love the syntax.
We are primarily a Ruby shop; our main apps are running on Ruby + Rails, our Slack bot is written in Ruby and our smaller projects are on Sinatra. It makes it really easy for us to re-use code and switch between different projects since they are all on the same language.
Because happiness. Testing via RSpec (mostly model and request specs), Factory Girl for fixtures, VCR for testing API responses, timecop, Redcarpet for Markdown rendering, Intercom gem for posting events.
