Tell us what’s happening:

Test 1 “You should have a booWho function” passes, but every other test fails, despite my console displaying the correct output.

Your code so far

function booWho(argument) {
  typeof(argument) === "boolean" ? console.log(true) : console.log(false);
}

booWho(true);
booWho(false);
booWho([1,2,3]);
booWho([].slice);
booWho({ "a": 1 });
booWho(1);
booWho(NaN);
booWho("a");
booWho("true");
booWho("false");

Hi

The instructions asks that the function return a value, not print to the console as you have done. Needs tweaking.
