so if you intend to use defrecord you must use protocols as well, correct?

You don’t have to. They’re separate mechanics.

But it’s common be cause it gives the record behaviors.

@jeff.engebretsen: but you can define ‘methods’ so to speak without a protocol?

No.

just what you get with maps.

Maybe some others. I’m not sure what all records get.

on ClojureScript you can use Object as a "pseudo-protocol" for adding arbitrary methods

@whistlerbrk: records create java classes behind the scenes so they are a bit more performant than maps

and if you want to provide polymorphic calls then you have protocols. with maps you can use multimethods (also less performant than protocols)
