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.
cool
Use single quotes unless string interpolation is required.
great solution! I like it, man!

This is surely clever, but probably shouldn't be used or marked as best practice. I'd have to performance test to be sure, but allocating an array on heap seems like it would be much slower than a branch with no array allocation. Maybe I'm wrong, in which case this would be a nice answer, but the bitwise and will always be better for both performance and readability.
If did that, than you should be proud of yourself. Constructing a algorithm to treat string dates ins't something trivial.
No

I know it's trivial, but how is mutating the original arrays being accepted as a valid solution?. Likewise for most of the other answers here
No
const?Yeah, very disappointing to see this top-rated with such an obvious error.
so elegant!
