Can you explain the difference between getters, setters, and properties in programming?
Sure! Getters and setters are methods used to access and modify the values of private variables, while properties are a more modern way to achieve the same functionality.
How do getters and setters work in a class?
In a class, a getter method retrieves the value of a private variable, while a setter method allows you to set or update that value, often with validation.
What are the advantages of using properties over getters and setters?
Properties provide a cleaner syntax and can simplify code by allowing you to access values like fields, while still encapsulating the logic.
Can you give me an example of how to implement them in JavaScript?
Certainly! In JavaScript, you can define a property using the get
and set
keywords within an object, like this: get name() { return this._name; }
and set name(value) { this._name = value; }
