How to Create the class in JS?
==============================
Keyword : class
Syntax:
	class ClassName{
		// class logic
	}

// creation of class

class Student{
    constructor(stuName,stuId){
        this.stuName = stuName;
        this.stuId = stuId;
    }
}


let/var/const ClassName = class(){
	//logic of the class
}

// creation of class

let Employee = class{
    constructor(eid, ename, salary){
        this.eid = eid;
        this.ename = ename;
        this.salary = salary;
        
    }
}
=========================================
How to Create the Object of the Class?
=======================================
Syntax:
	let/var/const object-reference-name = new Class-Name-Constructor(values for constructor parameters with comma separation);

// creation of class

let Employee = class{
    constructor(eid, ename, salary){
        this.eid = eid;
        this.ename = ename;
        this.salary = salary;
    }
}

// object creation
let employee1 = new Employee(122131,"Suresh",26000.0);

let employee2 = new Employee(121213,"Keerthi",25500.0);

console.log("The Employee1 Data = ");
console.log("Employee Id = ",employee1.eid);
console.log("Employee Name = ",employee1.ename);
console.log("Employee Salary = ",employee1.salary);
console.log("===========================");
console.log("The Employee2 Data = ");
console.log("Employee Id = ",employee2.eid);
console.log("Employee Name = ",employee2.ename);
console.log("Employee Salary = ",employee2.salary);
console.log("Employee Salary = ",employee1.salary);
==============================================
How To Create The Method in the class?
======================================
class ClassName{	
	data members
	
	method-name(){
		implementation
	}
}


class BankAccount{
    constructor(accountNumber,balance){
        this.accountNumber = accountNumber;
        this.balance = balance;
    }
    
    // method creation
    display(){
        console.log("The User Banking Creddentials are:");
        console.log("Account number = ",this.accountNumber);
        console.log("Balance = ",this.balance);
    }
}

const holder1 = new BankAccount(573602010007620, 28987.0);
const holder2 = new BankAccount(19283746520,1029.0);

holder1.display();
holder2.display();
==============================================================
class RandomClass{
    constructor(){
        this.a = 100;
        this.b = 200;
    }
    
    static p = 10;
    static q = 20;
    
    static sumData(){
        console.log(this.p + this.q);
    }
}

let rc = new RandomClass();

// rc.sumData();
RandomClass.sumData();
// rc.sumData();
==============================================
If two static methods in the class with same name?
==================================================
class myClass{
    constructor(a){
        this.a = a;
    }
    static display()
    {
        console.log("The Class variable = ",this.a);
    }
    static display()
    {
        console.log("Hello");
        // console.log("The Local Variable = ",p);
    }
}

mc = new myClass(200);
myClass.display();
// myClass.display(100);

=====================================================
Q: If an Instance method and static method with same name?
==========================================================
class myClass{
    constructor(a){
        this.a = a;
    }
    display()
    {
        console.log("The Class variable = ",this.a);
    }
    static display()
    {
        console.log("Hello");
        // console.log("The Local Variable = ",p);
    }
}

mc = new myClass(200);

mc.display();

myClass.display();

==================================================
If two instance methods in the class with same name?
=====================================================
class myClass{
    constructor(a){
        this.a = a;
    }
    display()
    {
        console.log("The Class variable = ",this.a);
    }
    display()
    {
        console.log("Hello");
        // console.log("The Local Variable = ",p);
    }
}

mc1 = new myClass(200);
mc2 = new myClass(300);

mc1.display();
mc2.display();
