Are getters and setters necessary in JavaScript?

Do I really need to use getters and setters in JavaScript?

Getters and setters are not strictly necessary, but they can help encapsulate and manage object properties more effectively.

What are the benefits of using them?

They provide a way to control access to properties, allowing for validation, computed properties, and easier debugging.

Can you give me an example of how to use them?

Sure! Here's a simple example:

class Person {
    constructor(name) {
        this._name = name;
    }
    get name() {
        return this._name;
    }
    set name(newName) {
        this._name = newName;
    }
}

This allows you to get and set the name property while keeping the actual property private.

Are there any downsides to using them?

One downside is that they can add complexity to your code, making it harder to read if overused. It's important to use them judiciously.
