ClearValues() public method?

[pha3z]

After calling SetValue() several times to set values and calling a script, I'd like to clear out everything I set, and then set new values before executing another script. Is there a reason there isn't a ClearValues() method on Engine?

Yes, because there's no tracking what you've set (or replaced). For fresh start either use new engine instance or try ShadowRealm.

How should ShadowRealm be used?

I looked at the Engine constructor, and it looks like there is a lot of allocation and setup going when you new one up. It seems unnecessarily expensive if you just want to reset to a starting state between frequent repeated executions.

Is there are practical way to reset to the starting state?

Here's example of the Shadow Realm.
