Ah, I see your question now. Prototypes maybe? I’m not nearly a good enough JS dev to have a reasonable guess at that specifically.

Being able to access class members using square bracket syntax with a variable also seems like it would make it really difficult to prove that something isn’t used. I’m thinking something unhinged like using parameters to build a string named after a class member and then accessing it that way.

Dunno, I would be curious if someone has a definitive answer as well.
