You fork it (The button on top right) and then you can run it.

I see it passed the tests but can't get it to work on the console in CodePen.
How do I run it?
Thanks

cool

The description says:

... or ... or ... or [] for Kotlin...  or ...

Same is happening in Kotlin, the instructions mention "-1 -1 -1" but the expected array lenght is 0.

Of course there's many programming languages and it's hard to explain what to return in each language. So in the description I read, that you had to return an integer array of {-1, -1, -1}, if v1 >= v2. But actually you need to return null. Because of that I got an error message:

• expected array was null.

When I looked at the kata test cases I understood my mistake.
