  const actions = () => {
    const remove = document.querySelector('.remove')
    const add = document.querySelector('.add')
    const count = document.querySelector('.count')
    
    const removeEvent = createEvent.prevent(remove, 'click', (_ev) => {
      state.count--
      count.innerHTML = state.count.toString()
    })
    
    const addEvent = createEvent.prevent(add, 'click', (_ev) => {
      state.count++
      count.innerHTML = state.count.toString()
    })

    // return all event for clean before unmount (event|[events])
    return [removeEvent, addEvent]
  }
  
  render(html`
    <h1>Counter</h1>
    <p>This component preserves the state after unmounting</p>
