What language should I learn next if I'm familiar with SAS?

The choice of language really depends on what you're looking to achieve with it. Don't just focus on ease, think about what you need it for. If you have a specific goal in mind, find a language that suits that best!

I've used R quite a bit and also had to learn SAS. Honestly, if you can handle SAS, you can tackle just about any language. And yes, SQL counts as a language too! Looking at Python would benefit you in the long run since it's very versatile and in demand.

I haven't used SAS myself but I hear that R is pretty user-friendly for statistical work, which sounds like your jam. Python is also a great choice, especially for data science and machine learning if you want to branch out further. You might also want to check out Julia if you're feeling adventurous!

If you're already using SAS, I'd say R would be the easiest next step for you. It's another stats-focused language so you won’t feel too lost. But if you want something that’s more versatile and widely used, Python is the way to go. I’ve worked with all three, and Python definitely opens more doors with its capabilities.
