How to access main object's property inside inner nested object?

Question

let obj = {
  a: "Kale",
  b: "kite",
  c: "citay",
  d: "dantay",
  allNames: {
    name1: obj.a,
    name2: obj.b,
    name3: obj.c,
    name4: obj.d
  }
};

error:Cannot access 'obj' before initialization

I want names in allNames object to be equal to values in outer object(obj), i.e.

name1: "kale"
name2: "kite"
name3: "citay"
name4: "dantay"

If I do it with this method:

allNames: {
    name1: this.a,
    name2: this.b,
    name3: this.c,
    name4: this.d,
}

Of course it'll be undefined .. so how to do this and not to make it look like hard-coded?
