Analyzer not recognizing getter or setter

Tell us what’s happening:
Describe your issue in detail here.

When I run the tests, it tells me there is no getter or setter defined.
Your code so far

// Only change code below this line
class Thermostat {
constructor(fahren) {
  this._fahren = fahren;
get temp() {
  return (this._fahren-32)*(5/9);
set temp(cels) {
  this._fahren = (cels*9) / (5+32);

// Only change code above this line

const thermos = new Thermostat(76); // Setting in Fahrenheit scale
let temp = thermos.temperature; // 24.44 in Celsius
thermos.temperature = 26;
temp = thermos.temperature; // 26 in Celsius

Challenge: Use getters and setters to Control Access to an Object

Link to the challenge:

You have two problems that I can see.

First, it tells you:

When instantiated with a Fahrenheit value, Thermostat should set the correct temperature .

They want the property to be called “temperature”, not “temp” or “fahren”. Typically the private member has the same name as the getter/setter, just prepended with an underscore.

Secondly, this formula looks wrong:

  this._fahren = (cels*9) / (5+32);

When I fix those, your code passes for me.

Thanks, yes, I did continue searching and found the hint that the name of the getter/setter needs to match the other code.
And yeah math isn’t my strong suit.


Yeah, for web dev, you don’t have to be a math genius, but having some basic math skills is good. I always say that most 12 year-olds know enough math for most of what we do. I think being able to invert a formula like:

C = (F - 32) * (5 / 9)

should be a good goal. I think very, very basic algebraic manipulation should be a good thing to have. If that is a struggle for you, I might look for some tutorial videos on basic algebra and formula manipulation. (I’m not even sure of the name here.) You don’t need a lot of advanced stuff (for most web dev jobs) but some basics will make your life easier.
