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.
Ignore means "treat it like it's not there", "do not process".
For 0's at the beginning and end of the input to become spaces in the output, you have to process them, which you are told not to do.
Not an issue, from my perspective.
Ignore means remove them in this case.
Oops. Thanks for reporting. Fixed.

For JavaScript is is Preloaded.WORDS.OK. Kata description updated by language.
use
preloaded::words@DM: the description needs effectively an update (or a comment in the solution setup?)
