const plus = createEvent()

const int = createStore(1).on(plus, n => n + 1)
const text = int.map(n => `current value = ${n}`)
const data = createStoreObject({int, text})

const IntView = createComponent(data, ({}, {int, text}) => <div>n = {int}</div>)

const IntHook = () => {

}

const App = () => (
  <div>
    <button onClick={plus}>click</button>
    <IntView />

const div = document.createElement('div')
document.body.appendChild(div)
