Jruby is already kind of an easy sell in big companies. It’s the quickness of rails with the familiarity of java.
I’m not trying to to sell JRuby to enterprises [well clearly, or else he wouldn’t be giving this talk at rubyconf].
JRuby can work well, even for startups - it’s just about choosing the best tool for the job.
Why might one choose JRuby?
- library support (in fact, we wanted Lucene for search!)
- extending the language without using C
- easy install
- don’t use textmate to code java
- casting can be tricky (java needs arrays to have only one type of object in them, ruby not so much)
