const model = 0

const actions = {

  increment: (state) => state + 1,
  decrement: (state) => state - 1,
  incrementBy: (state, increment) => state + increment,
  decrementBy: (state, decrement) => state - decrement,
}

const effects = {
  incrementIn: (actions, effects, delay) =>
    setTimeout(actions.increment, delay),
  incrementIn2Seconds: (actions, effects) => effects.incrementIn(2000),
}
