js - Prototype Inheritance

// This is a prototype , ye to become object

const proto = {

  

  // slogan : function(){

  //   return "this compnay is worst"

  // },

  changeName : function(newName){

      this.name = newName

  }

}

// creating harry object with the help of above prototype

// 1st way

const harry = Object.create(proto)

harry.name = "harry";

harry.role ="engineer";

harry.age = 24

harry.changeName("harry2");

// creating harry object with the help of above prototype

// 2nd way

const himanshu = Object.create(proto,{

  name : {value : "harry2ndway",writable: true},

  role : {value : "programmer2ndway"}

})

himanshu.changeName("harry.....");

/* -------------prototype inheritance------------------------ */

// #employee constrctor

function Employee(name,sal,exp){

  this.name = name;  

  this.salary = sal;

  this.experience = exp;

}

// creating slogan function and adding in employee prototype

Employee.prototype.slogan = function(){

  return `this company is of ${this.name}`

}

// creating object of employee with the help of above constructor

let employeeObj = new Employee('harry',2345456,34);

console.log(employeeObj);

console.log(employeeObj.slogan());

// #Programmer constrctor (inherit from employee constructor)

function Programmer(name,sal,exp,lang){

  Employee.call(this,name,sal,exp);

  this.language = lang;

}

// #inheriting employee prototype(slogan function) to programmer object

Programmer.prototype = Object.create(Employee.prototype)

// manually set constructor

Programmer.prototype.constructor = Programmer;

let programmerObj = new Programmer("rohan",2, 0 ,"java script")

console.log(programmerObj);
