How would you pass values between two different Hooks? See my two examples in the post (useSpring and useFriendStatus). Note they need to be always up-to-date

  With passing values between hooks do you mean "Make one hook depend on the value of another hook?". Because that seems like the functor 'map', or applicative 'apply'. Note, I don't really know what these springs are, but derived hooks could work like this: class MyComp extends ReactishComponent { fast = this.use(new Spring({ pos: [0, 0], config: "fast" })) // prim hook slow = this.use(this.fast.map(spring => ({ pos: spring.pos, config: "slow" }))) // functor map mid = this.use(combineTwoHooks((fast, slow) => computeMiddle(fast, slow), this.fast, this.slow)) // applicative render() { return ( <> <Point pos={this.fast.get().pos} /> <Point pos={this.slow.get().pos} /> <Point pos={this.mid.get().pos} /> </> ) } } The trick is functions that convert hooks into new hooks.
