Go vs JRuby: What are the differences?

Developers describe Go as "An open source programming language that makes it easy to build simple, reliable, and efficient software". Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language. On the other hand, JRuby is detailed 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.

Go and JRuby belong to "Languages" category of the tech stack.

"High-performance" is the top reason why over 439 developers like Go, while over 7 developers mention "Java" as the leading cause for choosing JRuby.

Go and JRuby are both open source tools. It seems that Go with 59.6K GitHub stars and 8.25K forks on GitHub has more adoption than JRuby with 3.31K GitHub stars and 829 GitHub forks.

According to the StackShare community, Go has a broader approval, being mentioned in 892 company stacks & 589 developers stacks; compared to JRuby, which is listed in 13 company stacks and 4 developer stacks.
