JS Object Getters/Setters

Defining Getters and Setters

JavaScript getters and setters manage property access dynamically.

What Are Getters and Setters?

In JavaScript, getters and setters allow you to define methods that are used to access and update the properties of an object dynamically. They provide a way to control access to an object’s properties by defining custom behavior when properties are retrieved or assigned values.

Defining Getters and Setters

Getters and setters can be defined using the get and set keywords inside an object literal or within a class. They are defined as methods, but you access them like properties.

Advantages of Using Getters and Setters

  • Encapsulation: They help encapsulate the internal representation of an object, allowing you to change the way properties are accessed and modified without changing the interface.
  • Validation: Setters allow you to implement validation logic before assigning values to properties.
  • Computed Properties: Getters can return computed values, enabling dynamic property calculation.

Using Getters and Setters in Classes

Getters and setters can also be used within JavaScript classes, providing a clean syntax for defining property access methods.

Conclusion

JavaScript getters and setters are powerful tools for managing object property access. They help enforce data integrity, encapsulate logic, and provide a flexible interface for interacting with object properties dynamically.
