Hi friend in this article I am going to describe what exactly encapsulation and emplemation in JavaScript

In a simple word encapsulation is defined as the wrapping up of data and method under a single unit.

 

Example

class Person {

  constructor(name, phone, email) {
    this.name = name;
    this.phone = phone;
    this.email = email;
  }

  getPersonName() {
    return this.name;
  }

  getPersonPhone() {
    return this.phone;
  }

  getPersonEmail() {
    return this.email;
  }

}

const ob = new Person("Mahbub Hasan", 88021344444, "example@gmail.com");
console.log(ob.getPersonName());
console.log(ob.getPersonPhone());
console.log(ob.getPersonEmail());
