Description states

More examples in the test cases.

This refers to the main tests. You can print the input to see what that is:

function common(a,b,c) {
  console.log(`a = ${a}`);
  console.log(`b = ${b}`);
  console.log(`c = ${c}`);
}

Both numbers are False when I try them in my code (that passed all the tests), so I guess it is not expected to be True. Maybe there is something else wrong with your code...

where are more examples?

Random tests are susceptible to input mutation - this is a kata issue. To pass the kata, don't mutate the input array.

It should work for random inputs too - Expected: [undefined], instead got: [105, 99, 74]

What to do with it? Doesn't pass random tests...

Hi all! Why is the number 76 expected to be true in tests? On the first pass, removing every second number and 76, the same with the number 368....
