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;
