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.
Basically this.
I for one like freedom units. They are very liberating.
I think the suggestion is change the units to metric
Not a suggestion.
Showing what the input is is up to the kata author/translator and you can't control it. If your code doesn't work, yes, I would check the input and see why it fails. Unless you want to guess why it fails.
Use console.log to see what the input is, check why your code fails, it is a problem with your code, not with the kata, next time use Question, not Issue.
The expected values are ok.
