Programming Language

Easily write cross platform systems tools, same power and low-level abilities as C or C++ but much easier to learn and work in, also the best GUI tooling I've ever seen.

Lazarus is a great cross platform tool for developing native applications for x86, x64, arm, Java target, etc.

Great for backend development, simplifies concurrent programming with multiple threads. Used in well known products like Docker, CockroachDb, Hugo, OpenShift and Gitea.

It worked well. I didn't know much about Ruby but I was quickly able to understand the code, make modifications and add new tests for the product we were building. One complaint... it tended to be a bit slow.

Microsoft offers a lot of documentation and also there is a lot of third party support. A problem though is that due to the sheer amount of information especially beginners can get lost easily.

easy to learn for a non programmer. and easy to use in more advanced environments if you start to work in production.

I built a big commercial product with Erlang

there are many free resources available to read. and it has a lot of information about Go it's the best place to begin for anyone. their I'm the first. besides it's golang's official web page.

Great Smalltalk implementation, you can compile it from source
