What's the difference between constructor property and instanceof method?

Tell us what’s happening:

  **Your code so far**

function Dog(name) {
this.name = name;
}

// Only change code below this line
function joinDogFraternity(candidate) {
if(candidate.constructor === Dog){
  return true;
  }
  else{
    return false;
  }
}
