Not really much useful in here. Some vague problem description related to keeping server-side and client-side code in sync and putting it in the same language solves that. How? I have no idea. Would protobufs and/or gRPC have achieved the same thing? Is this a unique problem to the web or not one that client/server apps have had since day one? I’m happy for the guy that he got a change through and the company believes it is positive but this seems like a PR fluff piece.
