Summary
Resources
Groovy is an agile and dynamic language for the Java Virtual Machine. Builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. Makes modern programming features available to Java developers with almost-zero learning curve
supports Domain Specific Languages and other compact syntax so your code becomes easy to read and maintain
makes writing shell and build scripts easy with its powerful processing primitives, OO abilities and an Ant DSL
increases developer productivity by reducing scaffolding code when developing web, GUI, database or console applications
simplifies testing by supporting unit testing and mocking out-of-the-box
seamlessly integrates with all existing Java objects and libraries
compiles straight to Java bytecode so you can use it anywhere you can use Java
As the official Groovy Project Manager and Spec Lead of JSR-241, standardizing the Groovy dynamic language, Guillaume LaForge spends his spare time bringing a versatile and agile environment to the masses and intiated the seed of Grails, the Groovy and Spring framework. He has co-authored Manning's successful Groovy in Action along with Dierk Koenig, one of the passionate Groovy developers.
In his profesionnal life, Guillaume Laforge is the Vice-President of Technology at G2One, the company sustaining and leading the development of Groovy and Grails.
