Ask HN: Which new programming language are you planning to pick up in 2019?

Rust!

New concepts, systems programming, seems to be getting some traction! Plus the book is awesome: https://doc.rust-lang.org/book/

I've started dipping my toes in Rust and Elixir. Rust because of the concepts like borrow checker, highly strict compiler, traits etc. Elixir because it is based on Erlang and is highly concurrent due to Actors, and overall a very clean language syntactically. Both of these are very different from the traditional OOP language that I'm using at work (C#).

Actually this is something I wanted to do last year but didn't get enough motivation/energy to actually pursue it. Now I've forced myself to actually do stuff with Rust for the first quarter of 2019 and have made some progress. If things go as per my timelines, I'll focus on Elixir & Rust in alternate quarters. I've found this to be much better than tackling both in parallel which I was doing last year.

As an aside, in the last month of 2018 I dabbled with Pharo/Smalltalk just to investigate its highly dynamic nature, improvement to dev productivity & how things really were supposed to work in real OOP. It was very impressive, especially considering we had something like in 80s & 90s.

Admittedly learning a new programming language is very far down my "teach myself something programming related" priority list, if I was to learn a new language it will either be Julia or Elixir.
