Use getters and setters to Control Access to an Object

JavaScript

Tell us what’s happening:

I got this right but I still don’t quite understand. When making temp = thermos.temperature;. The new Object thermos doesn’t have a temperature property.

If it was something like thermos.temp it would make more senses, right?. What am I missing something?

Your code so far


function makeClass() {
  "use strict";
  /* Alter code below this line */
  class Thermostat {
    constructor(F) {
    this.temp = F;
    }
    get celsius(){
      return 5/9 * (F - 32);
    }

    set celsius(C){
      this.temp = C;
    }
  }
  /* Alter code above this line */
  return Thermostat;
}
const Thermostat = makeClass();
const thermos = new Thermostat(76); // setting in Fahrenheit scale
let temp = thermos.temperature; // 24.44 in C
thermos.temperature = 26;
temp = thermos.temperature; // 26 in C

It looks like the exercise has too few tests in place. I can pass it with just this:

  /* Alter code below this line */
  class Thermostat {}
  /* Alter code above this line */

I think the intention is for you to make a temperature getter and setter, since that’s what the code at the bottom is using.

Same, I can basically bypass the test by putting in,

/* Alter code below this line /
class Thermostat {
constructor(Fahrenheit){
this.Thermostat=temp;
}
}
/ Alter code above this line */

This is the right way to access the value.
