I’ve always wondered what is the main difference between using rawequal() and ==? The API at https://luau-lang.org/library seems identical to me.
== fires the __eq metamethod if it exists in a metatable; rawequal does not.
It’s necessary if you need to make == comparisons within said metamethods, otherwise you get a stack overflow error.
See also: __index and rawget, and __newindex and rawset.

I knew rawget() bypasses __index metamethod. Thanks now I see, so they basically bypasses respective metamethods?
Correct.
It’s how you avoid stack overflow errors resulting from repeatedly calling metamethods unintentionally.
