HOW TO USE GETTERS AND SETTERS IN JAVASCRIPT

In JavaScript, getters and setters are special functions that allow you to control access to an object’s properties. They provide a way to encapsulate the internal state of an object, allowing you to add logic when getting or setting values. Here’s a guide on how to use getters and setters in JavaScript:

1. Creating a Basic Object:

Start by creating a basic JavaScript object. In this example, we’ll create a Person object with name and age properties.

2. Adding Getters and Setters:

Use the Object.defineProperty method to add getters and setters to your object.

Adding a Getter:

Now, when you access person.fullName, it will return the value of person.name

Adding a Setter:

Now, when you set person.fullName, it will split the value into first and last names and update the name and lastName properties.

3. Using Getters and Setters:

Now that you’ve added getters and setters, you can interact with your object as follows:

4. Class Syntax (ES6):

With the introduction of ES6 classes, you can also use the get and set keywords directly within a class definition.

5. Considerations:

Always remember to prefix private properties with an underscore (e.g., _name) to indicate that they should not be accessed directly.
Getters and setters provide a way to add additional logic or validation when getting or setting a property.
Be cautious about potential side effects when using complex logic within getters and setters.
