In most languages protobuf is eaiser because it generates the boilerplate. And protobuf is cross language so even if you are working in javascript where json is native protobuf is still faster because the other side can be whatever and you are not spending their time parsing.

In most languages I’ve worked in, there is no boiler plate for json either, and barely any for XML. You make a data class of some sort and it “just works”.

Not having that functionality is a weakness of a language or its support tools at this point, to me.
