javascript - After state is mapped to computed through mapState in vuex, how to write the original calculated properties?

Question

import {mapState} from 'vuex'

export default {
  data(){
      return {
          oldData: 0
      }
  }
  computed: mapState({
    count: state => state.count,
    newData(){
       return this.oldData + 1;
    }
  })
}

Do you write it like this?

Answer 1

import {mapState} from 'vuex'

export default {
  data() {
    return {        //你这里少写了
        oldData: 0
    }
  }
  computed: {
    ...mapState(["count"]),
    newData(){
       return this.oldData + 1;
    }
  }
}
