Can Js Have Getters And Setters Methods Named Same As Property

In JavaScript, you might be wondering if it's possible to have getter and setter methods with the same name as the property itself. Well, the good news is, you can indeed have getter and setter methods named the same as the property in JavaScript. Let's dive into how you can achieve this!

When you define a property on an object in JavaScript, you can also define getter and setter methods for that property using the `get` and `set` keywords. This allows you to have more control over how values are accessed and set on an object.

To create a property with getter and setter methods using the same name, you can define the getter and setter methods using a property name that matches the property you want to access. Here's an example to illustrate this:

const obj = {
  _count: 0,
  get count() {
    return this._count;
  },
  set count(value) {
    this._count = value;
  }
};

console.log(obj.count); // Output: 0
obj.count = 10;
console.log(obj.count); // Output: 10

In this example, we have an object `obj` with a property `_count`. We define getter and setter methods using the property name `count`. The getter method returns the `_count` value, and the setter method sets the `_count` value to the specified input.

By using getter and setter methods with the same name as the property, you can encapsulate the internal representation of the property while providing a more intuitive interface for working with the object.

It's worth noting that when you access the `count` property on the `obj` object, JavaScript automatically invokes the corresponding getter or setter method based on the operation you are performing (getting or setting the value).

Additionally, you can also use computed property names to dynamically create properties with getter and setter methods named the same as the property. Here's an example to demonstrate this:

const propName = 'age';
const obj = {
  _age: 0,
  get [propName]() {
    return this._age;
  },
  set [propName](value) {
    this._age = value;
  }
};

console.log(obj.age); // Output: 0
obj.age = 25;
console.log(obj.age); // Output: 25

In this example, we define a property name using a computed property name `[propName]`, which allows us to use a variable (`propName` in this case) to dynamically create properties with getter and setter methods.

In conclusion, in JavaScript, you can have getter and setter methods named the same as the property itself, allowing you to customize the behavior of accessing and setting properties on objects. This feature provides flexibility and control over how your objects interact with the outside world. Experiment with this concept in your projects to enhance code readability and maintainability.
