Why Groovy?

because its groovy :)

what are the options? 

  • JVM -> Scala, Clojure, Kotlin, Ceylon ? 
  • Other-> Ruby, Python, PHP

Reality Check


You are on existing project, Can you now :

  • Change Language ?
  • Change Framework/Architecture?
  • Add a Library?
  • Add a plugin to Build?


Why Groovy ?

Language overheads are minimal 

like, optional semicolon, optional return, optional function parens  etc.


Native language level support for map and lists,

def list = ["groovy", "spring", "hibernate"]


Operators overloaded intelligently 

list << "rocks"



WHY GROOVY ?

Sensible Defaults

Class public by default, Fields private by default, 

Methods public by default,


Automatic accessors (properties)





WHY GROOVY ?


Optional Typing  - def

Closures,

String templates,

Multiline strings,

 First class regex,

Awesome Builders (MarkupBuilder,
 SwingBuilder, AntBuilder)

Why With Spring-MVC and Hibernate?


Easy to add in existing projects

If you are just making the switch

Hate learning curve of yet another framework


ELSE ?

Use Grails, Gaelyk (GAE), Ruby on Rails, 
Django, Sinatra, Node.js .... 

pick your poison
