Hi vokoshyv,

Thank you for your feedback, I will add such edge cases especially for js langauge.

good idea! changed it to 'next'

The DocBlockr-style comments were really distracting, and did not offer much additional value. Beyond that, neat problem. I enjoyed it.

I liked the introduction to data structures. Instead of using 'rest' as a property for the contained object (which literally does include the 'rest' of the list), I think 'next' would be a better label. I believe that this will better motivate the coder's understanding of lists.
