Inheritance with prototype and class

//part 1
//create an object
// const user = {}
// user.name = "shopnil"
// user.age = 25
// user.intro = function () {
//     console.log(`I am ${user.name} I am ${user.age} years old`);
// }
// // console.log(user);
// user.intro()

//part 2
//create a constructor function object
// function User (name, age) {
//     const user = {}
//     user.name = name
//     user.age = age
//     user.intro = function () {
//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
//     return user
// }
// const shopnil = User("shopnil", 25)
// shopnil.intro()

//part 3
//create a constructor function object
// const userMethod = {
//     intro (user) {
//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
// }
// function User (name, age) {
//     const user = {}
//     user.name = name
//     user.age = age
//     user.intro = userMethod.intro.bind(user, user)
//     return user
// }
// const shopnil = User("shopnil", 25)
// const sidrat = User("sidrat", 18)
// // console.log(shopnil);
// shopnil.intro()
// console.dir(shopnil)
// console.dir(sidrat)


//part 4
//create a constructor function but the method store as a prototype
// const userMethod = {
//     intro (user) {
//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
// }
// function User (name, age) {
//     const user = Object.create(userMethod)

//     return user
// }
// const shopnil = User("shopnil", 25)
// const sidrat = User("sidrat", 18)
// // console.log(shopnil);
// shopnil.intro(shopnil)
// console.dir(shopnil)
// console.dir(sidrat)

//part 5
//store the outer method function into function's prototype method or property
// function User (name, age) {
//     const user = Object.create(User.prototype )
//     user.name = name
//     user.age = age
//     return user
// }
// User.prototype = {
//      intro (user) {

//     }
// }
// const shopnil = User("shopnil", 25)
// const sidrat = User("sidrat", 18)
// // console.log(shopnil);
// shopnil.intro(shopnil)
// console.dir(shopnil)
// console.dir(sidrat)

//part 6
//create a constructor function but the method store as a prototype
// const userMethod = {
//     intro (user) {
//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
// }
// function User (name, age) {
//     const user = Object.create(userMethod)
//     user.name = name
//     user.age = age
//     return user
// }
// const shopnil = User("shopnil", 25)
// const sidrat = User("sidrat", 18)
// // console.log(shopnil);
// shopnil.intro(shopnil)
// console.dir(shopnil)
// console.dir(sidrat)

//part 5
// store the outer method function into function's prototype method or property   and create the contractor function with new keyword
// function User (name, age) {
//     // const user = Object.create(User.prototype )
//     this.name = name
//     this.age = age
//     // return user
// }
// User.prototype = {

//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
// }
// const shopnil = new User("shopnil", 25)
// const sidrat = new User("sidrat", 18)
// // console.log(shopnil);
// shopnil.intro(shopnil)
// console.dir(shopnil)
// // console.dir(sidrat)


//part 6
//make a contractor function with method with the help of prototype in vanila java script way
// function User (name, age) {
//     this.name = name
//     this.age = age
// }
// User.prototype = {
//      intro (user) {
//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
// }
// const shopnil = new User("shopnil", 25)
// const sidrat = new User("sidrat", 18)
// shopnil.intro(shopnil)
// console.dir(User)

//make a contractor  with method with the help of new es6 class syntax way
// class User {
//     constructor (name, age) {
//         this.name = name
//         this.age = age
//     }
//     intro (user) {
//         console.log(`I am ${user.name} I am ${user.age} years old`);
//     }
// }
// const shopnil = new User("shopnil", 25)
// const sidrat = new User("sidrat", 18)
// shopnil.intro(shopnil)
// console.dir(shopnil)
//Create a class constructor with method from the scratch part 1 - part 6

//Start the inheritance part with vanila js way first
// Part 7
//create the inheritance with vanila javascript way

//Parent
// function Parent (name, age) {
//     this.name = name
//     this.age = age
// }
// Parent.prototype = {
//     intro: function(){
//         console.log(`Hello I am ${this.name} I am ${this.age} years old`);
//     }
// }

// //Child one
// function Child (name, age, birthDate) {
//     Parent.call(this, name, age)
//     this.birthDate = birthDate
// }
// Child.prototype = Object.create(Parent.prototype)
// Child.prototype.constructor = Child
// Child.prototype.hello = function () {
//         console.log(`hello`);
//     }

// //Grand Child
// function GrandChild (name, age, birthDate) {
//     Child.call(this, name, age, birthDate)
// }
// GrandChild.prototype = Object.create(Child.prototype)
// GrandChild.prototype.constructor = GrandChild
// const childThree = new GrandChild("sidrat", 14, "1999-05-20")
// childThree.intro()



// Part 8
//Create the inheritance with  class
class Parent {
    constructor (name, age) {
        this.name = name
        this.age = age
    }
    intro(){
        console.log(`Hello I am ${this.name} I am ${this.age} years old`);
    }

}

//Child
class Child extends Parent {
    constructor (name, age, birthDate) {
        super (name, age)
        this.birthDate = birthDate
    }
    hello () {
        console.log(`hello`);
    }
}
const childOne = new Child ("ridon", 23, "1999-05-25")
console.log(childOne);

//GrandChild
class GrandChild extends Child {
    constructor (name, age, birthDate) {
        super (name, age, birthDate)
    }
}
const grandChildOne = new GrandChild ("sakib", 23, "1999-05-25")
console.log(grandChildOne);
