- rust => basically, it's not new for me, I've done several small toy project with it, but I want to create bigger project with it.
- ruby => not new again, doing it only for work :((
- scala => this year will be quite interesting year for this language since its library adoption for 2.12 are still on going and who forget about dotty anyway ? Full stack development (frontend + backend) will be quite interesting
- typescript => I already try this, but still not getting anything quite done yet, sometimes it's still a bit awkward in getting some development tools working. It has some issues in getting js library working together since some js libraries weren't that friendly with typescript. (frontends)
