Comparing Groovy and JRuby
TS-4955

Life used to be so simple in the Java technology world. The only real decisions you had to make were which dozen frameworks to use in your project. Now dynamic languages have invaded Java technology land, and you have lots of choices. But to the casual observer, JRuby and Groovy look like pretty much the same thing, with slightly different syntax. Nothing could be further from the truth. Although they both share lots of commonalities, they are also quite different.

This session delves into those differences, providing the attendees with enough concrete facts to make decisions. It covers differences between type systems, extending the core JDK software, closures, and properties. It also covers metaprogramming differences, where the languages diverge the most, including open classes, code synthesis, mix-ins, interfaces, intercepting method missing calls, shadow metaclasses, and lots more.

Code is the focus of this presentation, with tons of examples. It will give attendees a clear picture of the real differences between these new kids on the Java technology block.
