Is the website only JavaScript? Are there other languages?

I don't exactly want to sign up right now 😅 but this challenge looks simple! I don't want to post the solution here (for the sake of people who want to try it), but it gives me hope that I can do some of the other ones :D

Hi! Thanks for your comment!

We are currently working on implementing multiple languages support, in the meantime is only JavaScript. But feel free to try or to share your solution in here! Here can be in any language that you want.

Best regards!
