// reducer const weight = (state = 160, action) => { switch (action.type) { case 'eat': return state + 10 case 'hungry': return state - 10 default: return 160 } } const store = createStore(weight) console.log(store.getState()) store.dispatch({ type: 'eat' }) console.log('我吃了一些事物') console.log(store.getState()) console.log('我饿了好几天') store.dispatch({ type: 'hungry' }) console.log(store.getState()) console.log('我又饿了好几天') store.dispatch({ type: 'hungry' }) console.log(store.getState())
reducer 里面使用switch语句根据传入的类型,输出新的状态
把reducer 传入 createStore(weight)
通过 dispatch 传入不同的类型,改变状态state。
store.dispatch({ type: 'hungry' })
通过 store.getState() 获取当前的状态
