Well, "isomorphic" JavaScript is not technically incorrect. They just didn't want to use the word "same". It's the same code on the server side and client side

Well, "isomorphic" JavaScript is not technically incorrect. They just didn't want to use the word "same". It's the same code on the server side and client side. So the client and server are isomorphic, because an object is trivially isomorphic to itself. It's a fine idea to run the same code on the client and server. No problem there. The word choice may be confusing because you expect there to be some deeper concept you are missing.
