Your code so far



class Thermostat{
constructor(temperature){
  this.temperature = temperature;
}
// setter
set temperature(celsius){
  this.temperature = (celsius * 9) / 5 + 32;
}
// getter
get temperature(){
  return (this.temperature - 32) * 5/9;
} 
}
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

Follow the example code, hope, you will get your solution there.

Are you missing an underscore something like this._example=something .

Use it wherever necessary as mentioned in the example code in your challenge .
