| ruby |

Ruby 3.0.0 was released on Christmas Day in 2020.

Ruby 3.0.0 covers those goals by

Performance

MJIT

Concurrency

Ractor

Fiber Scheduler

Typing (Static Analysis)

RBS

TypeProf

The Ruby team is moving into the right direction with JIT and Concurency. But, another “new” feature spot my eyes - Static Analysis.
I started using Ruby in 2007-2008 and I still remember the mood in Ruby-community at that time: dynamic typing is cool, and static typing just sucks. Time flies and even Ruby team decided to have some “Static types” features.

I am not sure whether it will help, since the Ruby community is not diversified as the Python community. IMHO Ruby equals to Ruby on Rails. Even PHP has a more diversified set of web frameworks: Laravel, Symfony, CodeIgniter, etc.
And when I am looking at the Ruby community from 13 years perspective I can say it will be really hard to bring here fresh air. And fresh air it’s not only yet another web framework, it’s another problem domain.
