Nested getter in JavaScript class [closed]

Is it possible to have getters nested in a class? If not, how would I achieve the desired behaviour?

For example:

class Character {
    constructor(){
        this.name = 'new character'
        this.skills = {
            acrobatics: {
                value: 10,    // user edits this value in app
                get modifier(){
                    return this.value / 2    // this has to dynamically change when this.value changes.
                }
            }
        }
    }
    get nameLength(){
        return this.name.length    // I'm aware that this works
    }
}
