Create JavaScript Object Using ES 6 Class

ECMAScript 6 introduced the class keyword to create classes in JavaScript. 

Now you can use the class attribute to create a class in JavaScript instead of a function constructor, and use the new operator to create an instance.

Create JavaScript Object Using ES 6 Class 

Let's create an Employee class:

class Employee {
    constructor(firstName, lastName, emailId, age){
        this.firstName = firstName;
        this.lastName = lastName;
        this.emailId = emailId;
        this.age = age;
    }

    getFullName(){
        return this.firstName + " " + this.lastName;
    }

    getFirstName(){
        return this.firstName;
    }
}

Now, we create an object of Employee class and access its methods:

const employee = new Employee('Ramesh', 'Fadatare', 'ramesh@gmail.com', 29);
console.log(employee.getFirstName());
console.log(employee.getFullName());
