What are ES6 classes and how do private variables work in JavaScript?

What are ES6 classes in JavaScript?

ES6 classes are a syntactical sugar over JavaScript's existing prototype-based inheritance, making it easier to create objects and handle inheritance.

How do private variables work in ES6 classes?

Private variables in ES6 classes can be created using the # prefix. They are only accessible within the class itself.

Can you give me an example of a class with private variables?

Sure! Here's a simple example:

class Person {
    #name;
    constructor(name) {
        this.#name = name;
    }
    getName() {
        return this.#name;
    }
}
const person = new Person('Alice');
console.log(person.getName()); // Alice
