I have been learning stats, SQL and R fir past 2 years. R is the only language i know and I like it. Now I want to learn a language like golang, Julia or Scala that can compliment my R. I chose R in 2016 and that's the best decision. Now for 2018 I want to enhance my programming skills.
Can you help me understand which language is more beneficial if I just want to stay in data and analysis field for ever. But I want to build complex desktop and web apps which have a lot of data related things.
Please any suggestion would do. Not python because it has same power and flaws like R. I want to compliment our enhance my knowledge not repeat it.
