You're being pedantic and doing gotcha argumenting.

Pass objects by ref, I said that to underscore its better than create new objects. I get it, its the only way, but theyre still passed by ref.

Yes, [a,b,...rest] =... is restructuring and creates new object.

Named params create new objects, it's better to pass args individually, the ref creation under the hood is not comparibly impactful.
