--- title: Use getters and setters to Control Access to an Object --- # Use getters and setters to Control Access to an Object --- ## Problem Explanation Getters and setters are critical parts of a class/object. They allow you to control their attributes from the outside. They will become more prominent when you get started with the Object-Oriented Programming unit (coming up!). For now, this exercise shows you how to manipulate them with ES6. --- ## Hints ### Hint 1 Create the class, Thermostat. You're going to put your constructor, getter, and setter in here. ### Hint 2 Give the constructor a parameter (which you can name anything you want). Set the parameter to an attribute of the same name. Remember, you are initially setting things in Fahrenheit temperature. ### Hint 3 Create a get method that converts the Fahrenheit attribute to Celsius. Use the formula given to you. ### Hint 4: Create a set method of the same name as the get method. It should have a parameter that accepts celsius temperature. Convert it to fahrenheit, and set it to the attribute. --- ## Solutions
Solution 1 (Click to Show/Hide) ```javascript function makeClass() { "use strict"; /* Alter code below this line */ class Thermostat { constructor(fahrenheit) { this.fahrenheit = fahrenheit; } get temperature() { return (5 / 9) * (this.fahrenheit - 32); } set temperature(celsius) { this.fahrenheit = (celsius * 9.0) / 5 + 32; } } /* Alter code above this line */ return Thermostat; } ```
