ES6: Use getters and setters to Control Access to an Object

function makeClass() {
  "use strict";
  /* Alter code below this line */
  class Thermostat {
    constructor(temperature) {
      this._temperature = temperature * 9.0 / 5 + 32 ;
    }
    
    get temperature() {
      return this._temperature * 9.0 / 5 + 32;
    }
    set temperature(newTemperature) {
      this.temperature = newTemperature * 9.0 / 5 + 32;
    }
    
  }
  /* 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

You need to rename your this.temperature to a different property name than the the getter/setter. That is causing a conflict with the getter/setter of the same name. You can use the still use temperature as a parameter for the constructor.

    set temperature(newTemperature) {
      this._temperature = newTemperature * 9.0 / 5 + 32;
    }
