I can't log into my account

I’ve tried logging into my account but nothing happens, i’ve tried logging with both Git-Hub and Google, still nothing it just keeps loading.

Your code so far


// Setup
function abTest(a, b) {
  // Only change code below this line
  switch (a<0 || b<0) {
    
  }
  
  
  // Only change code above this line

  return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));
}

// Change values below to test your code
abTest(2,2);
