Tell us what’s happening:
It shows Thermostat should be able to be instantiated. error.

Your code so far

/* Alter code below this line */
class Thermostat {
get temperature()
    return ((5/9)*(this.fahrenheit-32));
set temperature(Celsius){
/* Alter code above this line */

const thermos = new Thermostat(56); // setting in Fahrenheit scale
let temp = thermos.temperature; // 24.44 in C
thermos.temperature = 26;
temp = thermos.temperature; // 26 in C
