Making The DOM Declarative

React gave us a great tool for building UIs declaratively by abstracting away the details of putting DOM trees together and adding events to them. When you use React, you rarely have to use imperative methods like appendTo and addEventListener directly. But what about the rest of the DOM's imperative APIs? In this talk, we'll explore how we can extend what React taught us about making the DOM declarative to other imperative APIs as well!
