Vuex根据state 生成 getters 、mutation

const state = {
  name:'',
  age:11
}
const _getters = {}
const _mutations = {}
for (let k in state) {
    _getters[k] = state => state[k]
      // mutation 以set开头加state名驼峰
    _mutations['set'+k.replace(/[a-z]/, (L) => L.toUpperCase())] = (state,payload)=>{
        state[k] = payload
    }
}
const actions = {
  action(context){
      context.commit('setName','TOM')
  }
}
const getters = {
  ... _getters,{getter1(){},getter2(){}}
}
const mutations = {
  ... _mutations,{mutation1(){},mutation2(){}}
}
const store = new Vuex.Store({
    state,getters,actions,mutations
})
export default store
