Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Not a problem at all, that passed the tests, thanks!
In javaScript my code passing every test, basic and random, except for the last 2 Basic Tests where x = [], or x = [0.0].
When I run my code in the console however it is returning "0: the car didn't move.".
Isn't that the expected return for those values of x?
