This is my impression. Having used Excel and having a decent math background, FP seems easier to wrap my head around than OOP. This would be an interesting topic for a new thread.
I get what you are saying and it makes sense. I made the plan I did because I didn't know where to start and figured focusing on a sequence of languages would be a good way to get a solid foundation.
But I agree, once I have the basics down, I should just start executing and learn new languages and frameworks as needed.
