Reactive helpers and other utilities shared by HomeLib programs.

whenever

whenever activates work while one or more MobX conditions are true. The activation callback may return any disposer; it runs when a condition becomes false or when the outer reaction is disposed.

const ready = whenever(() => sensor.ready && light.ready);

const dispose = ready.then(() =>
  sensor.onMotionDetected(() => {
    light.turnOn();
  }),
);

.autorun() and .react() use the same activation lifetime for a MobX autorun or immediate reaction. All three methods return a disposer for the whole condition chain.
