 ## Description
 
 Basic idea is to develop a Project by mixing Java & Javascript code or even all in Javascript relying on the  [Nashorn Javascript engine](http://www.oracle.com/technetwork/articles/java/jf14-nashorn-2126515.html) embedded in JDK from Java8. This powerful engine enable Javascript language in JVM and allows to access to every java class either from JDK and external JAR(s) in a pretty straightforward way.
