Understanding Getters and Setters in Programming
Getters and setters are essential concepts in object-oriented programming that allow controlled access to object properties.
What are Getters and Setters?
Benefits of Using Getters and Setters:
Simple Examples:
Consider a JavaScript object named Person:
class Person { private name; private age; constructor(name, age) { this.name = name; this.age = age; } get name() { return this.name; } set name(newName) { // Validate new name before assignment if (newName.length > 0) { this.name = newName; } } get age() { return this.age; } set age(newAge) { // Validate new age before assignment if (newAge >= 0) { this.age = newAge; } } }
In this example, the properties name and age are private and can be accessed and updated via getters and setters.
