The code structre is quite simple:

class A {
    b = 1
    c = {
        d () {
            console.log(this.b) //=> undefined
            //how can i access b here?
        }
    }
}

I would prefer a not so hacky workaround since this is a core piece of code for the project i am working on

You could use an arrow function to preserve this where the function is being declared:

class A {
    b = 1
    c = {
        d: () => console.log(this.b)
    }
}

const a = new A;
a.c.d();
