Potential Bug in Verify an Object's Constructor with instanceof

Tell us what’s happening:
Is this a bug? I think I’m following syntax from examples exactly…

Your code so far

/* jshint expr: true */

function House(numBedrooms) {
  this.numBedrooms = numBedrooms;

// Add your code below this line

let myHouse = House(5);

myHouse instanceof House;

Link to the challenge:

Your missing a key word here in front of House(5) which will make myHouse an instance of House.
