Is it a good time to learn Ruby? I mostly do React and Node + Java work professionally It can be fun and it's as close as Smalltalk will probably get to mainstream acceptance, but if you are hoping for a lucrative commercial skill then probably you have missed the boat. Ruby is mainly used for two what most would now consider legacy things, Rails based websites and Chef based infrastructure. There is still some money to be made in maintenance of course and will be for a few years but the sun is definitely setting on Ruby. But 10 years ago it was super-hot.
