javascript loops 'for in' and 'for of ' are not working, upgrade ?

Hello,

I found out that the on board JS interpreter does not work with loops like 'for in' and 'for of '.

Is it planned in a near future tu upgrade the on board JS interpreter to a more feature-rich version ?

Thank you and
Laurent

You don't state which version of Advanced Renamer you are using. I am not having problems using the 'for in' and 'for of' in version 4.
