Groovy Or JRuby

clipped from jroller.com To Groovy Or JRuby Currently, in the Java world, we have two main scripting languages, Groovy and JRuby. Learning the syntax is usually the simple task, but it is important to understand that it does not end there. In order to really know how to use the language, we need to know all the different popular frameworks that comes with it, idioms on how to use it, and so on. what should a developer learn? Should it be Groovy or JRuby? Both have a very active community and very interesting frameworks that come with them - Grails in Groovy and Ruby on Rails in JRuby/ruby. The question is an open question to the community, ruby it can be used both on the Java world using JRuby, and in future possible projects that will use only ruby, The main thing that I currently think about is this: with Groovy, moving from Java to Groovy seems to feel more natural, Groovy grew out of Java, which gives it a big boost in terms of learning curve (Grails feels like that as well).
