It seems "Array find from last" is implemented: https://github.com/Samsung/escargot/blob/master/src/builtins/BuiltinArray.cpp#L1848

I think the list could be updated with it.

Is there some feature you would prefer to be implemented sooner? Temporal is currently in progress.

zherczeg avatar Jun 10 '22 11:06 zherczeg

I checked the "Array find from last". I also see a lot of references for realms, is that also implemented?
