Get & Set

Get & Set

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

We'll cover the following...

Using get Keyword

Let’s revise our knowledge for this keyword:

Press + to interact
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 is by using the get keyword.

Example

Let’s take a look at an example implementing the get keyword.

Press + to interact
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)
