How to avoid nested define data property in vue js

Question

Imagine there a object listed on data propery like this:

 data(){
     return {
      fruit: {
       grape: {
        purpleGrape: {
          price: '$5',
          showPrice: () => { console.log(this.fruit.grape.purpleGrape.price) }
        },
        greenGrape: {
        ....
        }
       }
      }
     }
}

is that another way to simplify the showPrice function that use this.fruit.grape.purpleGrape.price to get the price instead ? I want to use this keyword that refers to the object it belongs to like :

showPrice: () => this.price

But it doesnt work, I just want to simplify this nested thingy → this.fruit.grape.purpleGrape.price
