Eh, prototypes share, instead of create, method references. I guess you can use delegate objects too though unless you're just doing pure functions.

Sure, but imo unless one is creating very many objects each with their own set of functions it's not really a significant issue.

Sometimes programmers spend way too much time optimizing code which doesn't really need it.

In my experience how data is structured is almost always the most important factor when it comes to performance.

Good data structure + simple code === performance.
