My main language is JavaScript, but for an easy/medium challenge I'm definitely willing to give Python, Haskell and Go a chance.
In all honesty I'm impressed with these challenges and love reading others' solutions, but I'm curious what the response will be at this level. For a serious developer these problems definitely are solvable, but many with such skills already have plenty of work to do.
I can barely find time to do simple Codewars challenges in between work and my hobby projects, let alone larger ones like these.
Anyway, as long as people take on the challenges I'll be reading their solutions, so don't let my inability to participate home anyone back :)
