What are the advantages of Getters and Setters

Getters and setters offer several advantages in object-oriented programming, particularly in JavaScript:

1. Encapsulation: They help encapsulate the internal state of an object by providing controlled access to properties. This ensures that the internal representation of the object is hidden from outside code.

2. Validation: Setters can include validation logic before assigning a value to a property, ensuring that only valid data is set. This helps maintain the integrity of the object’s state.

3. Computed Properties: Getters allow for dynamic calculation of property values based on other internal properties or states. This means that you can provide a derived value without storing it explicitly.

4. Controlled Access: By using getters and setters, you can control how properties are accessed and modified, allowing you to implement additional logic or side effects when properties are read or written.

5. Read-Only Properties: Getters can be used to create properties that are read-only. This means you can expose a value to the outside but prevent it from being modified directly.

6. Backward Compatibility: Getters and setters can help maintain backward compatibility. For example, if the internal structure of an object changes, you can still provide a consistent API to the outside code using getters and setters.

7. Improved Debugging: With controlled access through getters and setters, you can easily add logging or debugging code to track changes to property values.

8. Consistency: They allow for consistent and predictable property access patterns, which can lead to more reliable and understandable code.
