How to compute a property value based on other property values "inline" during creation of JS object literal?

Question

I want to compute the full property as a result of the first and last properties in a single step, like so:

const name = {
  first: 'John',
  last: 'Doe',
  full: `${this.first} ${this.last}`, // undefined
}

But name.full is undefined.

What am I doing wrong?

const name = {
  first: 'John',
  last: 'Doe',
  get full() {
     return `${this.first} ${this.last}`;
  }
}
console.log(name.full);
