Not Able to use let cooldown = new Set();

For some reason. I been trying to do a command that has to require (“new Set();”)
and for some reason it would not work i was wondering if this has to do with the website editor it self or its something I’m missing

Does it actually not work, or is it just a linting warning? If it’s the latter then add /* global Set */ to the top of your code. If it’s not working, make sure you’re using a version of Node that supports Set.

I saw other topics and i fixed it,
it was the liniter.
