Better and worst coding language to learn?

Generally, you want to go for a language that isn't very verbose (Ruby, Python, Elixir/Erlang). These sorts of languages usually have stronger functional aspects to them and learning funcitonal programming will certainly help you out in the long run. I personally found that OOD was easier to learn with a more verbose language but ymmv. My advice would be to look around at different languages, after all they're just a means to an end. Good luck.
