How does vue computed assign values to variables in objects in data

data(){
    return{
        a:{
            b:null
        }
    }
},
computed(){
    "a.b"(){
        return "ab"
    }
}
?

is there something wrong with your grammar?
besides, 'a.b' is just a string, and A.B is two things.


the "A.B" on the first floor is a string. In fact, it can be written in watch. But you can't do it in computed if you don't know it.


it will be better to write down your reasons for doing so next time

abc: {
        get: function () {
          return ''
        },
        set: function (newVal) {
          this.a.b = newVal
        }
      }

use the set method
when you perform the this.abc=., to abc operation, the a.b in your data will change (guess you should be this requirement)
