Arc vs JRuby: What are the differences?
What is Arc? A dialect of the Lisp programming language developed by Paul Graham and Robert Morris. Arc is designed for exploratory programming: the kind where you decide what to write by writing it. A good medium for exploratory programming is one that makes programs brief and malleable, so that's what we've aimed for. This is a medium for sketching software.
What is JRuby? 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.
Arc and JRuby belong to "Languages" category of the tech stack.
JRuby is an open source tool with 3.32K GitHub stars and 830 GitHub forks. Here's a link to JRuby's open source repository on GitHub.
According to the StackShare community, JRuby has a broader approval, being mentioned in 13 company stacks & 4 developers stacks; compared to Arc, which is listed in 7 company stacks and 6 developer stacks.
