  const [self, update] = initStore({
    count: initialValue,

    increment() {
      increase(1)
    },

    decrement() {
      increase(-1)
    }
  })

  // private
  function increase(delta: number) {
    update(() => {
      self.count += delta
    })
  }
  
  return self
}

function Counter() {
  const
    store = useStore(createStore),
    increment = useCallback(() => store.increment(), []),
    decrement = useCallback(() => store.decrement(), [])

    <div>
      <label>Counter: </label>
      <button onClick={decrement}>-</button>
