In hindsight .map makes a lot more sense. I started this with the intention of finding duplicates, then replacing in another step. When I realized the .indexOf to .lastIndexOf comparison, I should have stepped back and looked for a different solution (.map) than .reduce.

@jhoffner is there an issue with the description? It shows both in the kumite, but I'm guessing it's handled on the kata when a language is selected.

@jhoffner thanks for the feedback. I added code examples in both JavaScript and CoffeeScript. Please let me know if there's anything else.

Looks good. One thing is the description. It is shared acrossed all languages. The current language example is a little generic right now. We could have a javascript and coffeescript version.

All you need to do is create both code blocks back to back, and the system will filter out the languages that aren't relevant when shown to a user.

Is there anything else I need to do for this translation to be accepted?
