proto inheritance from ES6 class [duplicate]

Answer 1

I was also interested on how to inherit in prototypical way from ES6 class, just to understand more in JS and here what I can propose:

class Parent {
    constructor(data){
        this.#setPrivateProperty(data);
    }
    #privateProperty = "Parent private property";
    #setPrivateProperty = (data)=>{
        this.#privateProperty = data;
    }
    parentPublicMethod = ()=>{
        console.log("Parent public method responded:", this.#privateProperty);
    }
}

function Child(data, parentData){
    this.__proto__ = new Parent(parentData)
    this.childPublicProperty = data;
}

Child.prototype = Parent.prototype;
Child.prototype.constructor = Child;

let c = new Child("Child data", "Parent data");
 // Output: "Parent public method responded: Parent data"
c.parentPublicMethod();
// Output: "Child public property value is: Child data"
console.log("Child public property value is:", c.childPublicProperty); 
// Output: "1. Instance of Child: true 2. Instance of Parent: true"
console.log("1. Instance of Child:", c instanceof Child, "2. Instance of Parent:", c instanceof Parent);

I will be very grateful to those people, who will criticize this code sample and maybe we get some more details. Thanks to All in advance!!!
