10.Brevity: a 40% code reduction for Groovy from Java, but what about the slowdown in execution time?
9.Yep, ranges are cool! Makes Groovy code look more like Python.
8.Beans: do you really need properties? Why not just code directly to the field?
7.Expando: Wow, just like Ruby open classes.
6.Grep: just use Unix (or call it from Perl)
5.Spring integration: better than Java.
4.Builders: Groovy truly innovated here, though Ruby long ago copied them.
3.Unit tests, mocks, stubs: better than Java.
2.Closures: many languages have them. Use Scala if you also want variable hiding!
1.ExpandoMetaClass: better than Java. In fact, if you’re a Java programmer and need to stay on the JVM, then Groovy could be for you. But after a while, you might get itchy fingers and try out Python/Ruby, Scala, Haskell, Smalltalk, Scheme/Lisp, APL/J/K, etc, then wonder why you stayed with Groovy for so long!

Thanks, Dierk,

Very true. I tried to give credit where credit was due, but may have missed a couple. If you can let me know what I missed, I’ll be happy to site your work.

Groovy In Action is an excellent book, one you should be proud of, as I mentioned in the “Expando” section.

Buy it! Now!

Hi, great post. When you quote example from the Groovy in Action book literally, you should give credits.
cheers, Dierk

Re: using Spring within Groovy without a single bit of XML configuration

Check out the Groovy documentation:
http://groovy.codehaus.org/Using+Spring+Factories+with+Groovy

Look for Annotation Approach and BeanBuilder Approach – both let you leave the XML at home.
