Getters in Classes
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.
12345678910111213class Product { constructor(name, priceCents) { this.name = name; this._priceCents = priceCents; } get price() { return (this._priceCents / 100).toFixed(2); } } const item = new Product("Headphones", 2599); console.log(item.price); // "25.99"
