________________________
//define the fn
function a(){
return "Loading"
}
//call the fn
console.log(a())
________________________
the fn return "Loading" as they asked , but the challenge not passed ,

Answer 1

I passed this challenge some days before and now the same code is failing. We can say this is a bug.
It's not the first one, many others have already been fixed, so we have to be patient and check again after a while.
