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.
Yeah, I isually prefer being explicit. :)
This is very similar to my solution, but I used
Array.prototype.map
. After a bit of reading, I realizedforEach
is more appropriate.map
returns the resulting array, which I don't need.I like how expressive this code is. Most functions (including mine) leave the
rounds
implied in one expression.By editing a built-in prototype, you're assuming that by the time you need it, nobody else has done the same thing that you just did (but perhaps they figured "capitallize" would output 'nIfTy'). You're opening your code to error, or introducing error into someone else's code.
