> How do you compose two base classes into a subclass?

In most other OOP languages besides JS, the obvious answer would be to use traits.

Traits are okay: React 'Mixins' which I mentioned in my parent post are basically traits but at the framework level, which allows them to be smart about composing/merging the use of framework functionality normally accessed by overriding superclass methods (eg. componentDidUpdate). Traits still have the composability issues I mentioned for React Mixins: how do you avoid collisions between the namespaces of different traits while still allowing some to compose others?

Hence why I've been playing around with class decorators and friends to try and figure out a nice way to do method modifiers, traits, etc.

But I got sidetracked with "but howtf do I make typescript understand the resulting signatures" and then got nerd sniped by something else.

Hopefully eventually I'll get back to it.

If you want to understand what Hooks are for, I wrote this piece:

I hope you find it helpful!

Hooks aren't _quite_ like traits or mixins or anything else. You can apply the same Hook multiple times and pass values between them. That's what makes them powerful.

Look at my last demo.
