yeah, some of the exercises are like the following:
```
function helloWorld() {
return "";
}
helloWorld()
```
but those sorts of obvious examples are mostly in the beginner exercises, so I wonder what the distribution of the correct answers was. If it was guessing based on function stubs, the prediction would be that correct answers would be clustered around the beginner exercises, and that as the exercises advanced in difficulty, there were fewer correct answers.
