[00:57:13] Jared "just" starts generalizing on how folks might do JavaScript interop

Jared makes generalizations here that work well for many cases but do not apply for every situation. For example, interop with UI tools such as a map would make more sense with custom elements rather than ports.

Check out Dwayne's post on Discourse explaining how ports are used in Qoda.
