Purpose
A nicer way to use mixins that doesn't look like Clojure.
Installation
npm install mix-townUsage
TypeScript
// Import the library and types
import { mix } from "mix-town"

// Make some mixins

}
// Apply said mixins.
const base = mix(HTMLElement)

class MyClass1 extends base {}
// Equivalent without the `mix` helper.
