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.

or not source.datathis line would cause an exception to be thrown in the valid scenario where source.data is zeroCool, but algorithm is O(n^2) where a straightforward linear approach is available.
very nice
This seems to be an O(n^2) solution, where a straightforward O(n) solution exists.
Nice approach. Perhaps .forEach() or .reduce() would be more appropriate than .map() here as we're not actually creating a new array.
