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.
Get started now by creating a new collection.
The basic implementation of that is enough to pass the kata, but... you have to avoid performances overhead in your implementation otherwise you may not pass the tests. So "keep it simple/stupid", but hunt for useless operations.

When there is only one parameter, the parentheses may be ommited. Similarly, when there is only one expression and this expression is returned, the curly brackets and return keyword may be ommited.
Interesting solution. Here are my two cents. Ternary operator can be removed. Just return the result of the comparison directly. Also, consider using strict equality for stylistic reasons.
