i added random tests to JavaScript

Haskell fork added with random tests.

Haskell fork adding random tests.

After re-reading the description, I've noticed that the description doesn't actually specify the PID of the root process. The example has a root PID of 1, but the only concrete specification is that the PPID of the root is -1 and that the PID of any process is greater than its PPID.

I can update the description to add that note about the root process PID always being 1, or I can update the tests to have root PID's that aren't 1. However, if I go with the latter root, a large portion of the solutions (including the author's) will be invalidated.

invalidated

I thought the same as you. Now we've learned!

Sorry, I wasn't sure what the spoiler flag was. I will mark applicable posts in future! Thank you for the feedback.

Please use spoiler flag next time.

"" is a string object. string objects have a method join(iterable), that produces a string of all elements in iterable seperated (or joined) by whatever the string object's value was.

>> "!".join(["I", "AM", "AWESOME"])
I!AM!AWESOME

I don't understand why the " " before ".join", can anyone explain?

I didn't know you could put all these in one line #based

Yes you're supposed to do that ; it's best practice :) See the fork D:)
