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.
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.
