I didn't realize that using console.log on Codewars would show you your log as well as run your code. New here, as you can see. Thanks for the tip.

console.log

I learned a lot from this one. It would be nice to see what the inputs are when the tests are failing, but having to guess led me to do some research I wouldn't have otherwise done.

I'd love to tell you, but I have not 'earned' access to see the code.

This is magic. Would anyone be kind of enough to explain what's going on in this code? Especially the recursive part?

thanks :)

This kata was challenging for me, but I enjoyed it very much and learned a lot. Also, I think this one was very well crafted. A complex problem to solve, but not because it was hard to figure out what the problem was asking for. Well done.

This is very impressive. I hope to eventually to be able to work with regexps like this.
