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.
Beautiful <3
Brilliant!
Beautiful, declarative solution. Love it!
This is brilliant
Love defining swapCase and isLowerCase variables. Makes it easier to reason about.
This is brilliant.
Just want to say that Math.pow() is no longer considered best practice. Just use the exponentiation operator in ES6. So it would be (c ** 2).
Love your functional solution.
.splice() mutates the original array; .slice() is what you're looking for.
Love the descriptive argument names!
