RE: To Groovy or to JRubyShay Banon ask the question : To Groovy or to JRuby?
It seems that these days, whenever we see Groovy mentioned in blog post, it must be compared to Ruby or more specifically to JRuby. Then, in the comments, we have some Groovy lover express that Groovy is better than JRuby for the Java developer. What is funny is that people who are working on JRuby suggests that you try both and see for yourself.
Now that Groovy achieved to deliver a 1.0 version (and now a 1.1), it seems that this trend is increasing... Groovy advocate are becoming more vocal about their stuff. Instead of pushing Groovy/Grails for what it's worth, they are pushing it by saying how easy it is to learn compared to Ruby/Rails for a Java developer perspective. This is the argument that's being repeated over and over! And, as we see in some post comments, this makes some manager feel better.
This makes me feel sad!
Now this argument has some truth in it, but this does not necessarily make Groovy a better alternative than JRuby for scripting the Java platform. Learning a new language is always a good thing... Be it Groovy, Ruby, Python, etc. You never really loose by learning a new language... You never really loose by learning a new API, a new framework. Learning new things makes you a better programmer.
This is why I prefer Ruby/Rails than Groovy/Grails... It's not because Ruby/Rails is superior, it's just that learning a completely new language/framework help me open my mind to new ways of thinking. Learning Groovy will also do that, but to a much smaller extent. This will help me become a better programmer... Even better it will keep my mind awake enough to not become a dinosaur who know only one language/framework.
And to the manager that may read this... Having developers who have an open mind and bring new ideas is way better than having developers that will not stray away from their main comfort zone. It cost less in training and allow you to get advantage of new technologies as they become mainstream instead of missing the boat.
Don't take this post as telling you to choose JRuby, like Charles Nutter said, "don't let anyone make the choice for you."
