JavaScript is one of the most popular languages used by programmers all around the world. In this course, you'll be introduced to the Object-Oriented Paradigm of JavaScript. The course will discuss OOP in both, ES5 and ES6 versions of JavaScript. It begins with a basic introduction to what Object-Oriented programming is, followed by its comparison to other languages. It then introduces the new  OOP features available in ES6 version and compares it to the ES5 version. The course then discusses objects in JavaScript followed by the use of function as objects in OOP. It goes over the interesting concepts of prototype objects, data encapsulation, and classes. It then delves into the more complex concepts of inheritance in both the versions, including prototypal inheritance, prototype chaining, method overriding and mixins. The course is filled with interesting illustrations to help in your understanding of the concepts as well as numerous quizzes and exercises to help you practice.

# Using `get` Keyword
In the [previous](https://www.educative.io/collection/page/5429798910296064/5907042445295616/4851422833147904) lesson the following code was discussed:

var employee = {
  
  name: 'Joe',
  age: 28,
  designation: 'developer',
  //function returning designation of the employee
  display() {
    return this.designation //using this to refer to the "employee" object
  }
}
//this will display the designation
console.log(employee.display())

Here the function `display()` was being used to *get* the value of the *property* `designation`. Another way to do this by using the `get` keyword. 

## Example
Let's take a look at an example implementing the `get` *keyword*.

var employee = {
  
  name: 'Joe',
  age: 28,
  designation: 'developer',
  //function returning designation of the employee
  get display() {
    return this.designation //using this to refer to the "employee" object
  }
}
//this will display the designation
console.log(employee.display)

### Explanation
You must be wondering what the difference is since the function definition is exactly the same as before apart from the use of the *keyword* `get`. Now look closely at **line 12** in both the code executables above. 

See the difference? 

Using `get` changes the way the *function* `display()` is called. It is now called exactly how a *property* is called: `employee.display` whereas without `get` it is called as a *function*: `employee.display()`.

This lesson teaches how to use the "get" and "set" keywords in JavaScript.
