Best: working with F#, hands down the best development experience ever for me!

Worst: this is a little harder, but I’d give the questionable honor for any experience working with one of our juniors on JS... or just working with SwiftUI - mobile development hasn’t been a good experience for me by any means so far, but working with SwiftUI has been the worst of them.

// EDIT: I just remembered it was this year when I needed to do stuff with Python. EASILY the worst development experience...
