Actually yeah, that doesn't sound very useful. Math (significant math), encoding and hashing being done on the client sounds like a poorly designed application

Actually yeah, that doesn't sound very useful. Math (significant math), encoding and hashing being done on the client sounds like a poorly designed application. Same for templating on the server -- which I assume you mean manually compiling templates using a library, and sending the result to a client, perhaps as a property of a JSON object.
