Learn Getters in Classes | Inheritance and Encapsulation

When you want to control how a property is accessed in a class, you can use a getter method. Getters allow you to define special methods that are accessed like properties, using the get keyword. This lets you compute a value, validate data, or even hide internal implementation details, all while letting users of your class interact with the property as if it were a regular field. With getters, you can make your classes safer and more flexible by controlling what happens when someone tries to read a property.

class Product {
  constructor(name, priceCents) {

  get price() {
    return (this._priceCents / 100).toFixed(2);
  }
