Use javascript or groovy?

Hi all,

I'm just starting out with Ready API and wondering if it's better to use Groovy or Javascript? Are both equally well supported across the Ready API suite? Groovy has been used in SoapUI for longer so I thought that might be the more battle tested of the two.

Also from this post (though old) indicates Groovy is backwards compatible with Java which would be nice to have

Thanks for any help
