Not an expert in JS, but maybe this makes sense in JS where everything is passed as objects anyway and having a single param is often more readable there.

But in native languages like C/C++/etc, this pattern usually hurts performance. Separate arguments go into registers (faster but depends on number of arguments), while structs often involve indirection, and sometimes alignment/padding issues. Also, passing a const struct doesn’t guarantee the fields inside are truly const.

That said, it's context dependent. If you're passing stuff through multiple layers or want a more stable function signature, using a struct can be cleaner. Just not something I’d generalize to any language or any use case.
