I think that it is great that you are wanting to learn actual code! While some of the coding logic skills no doubt transfer from block code to real world, in general, block coding just isn’t as transferable as text coding.
Anywho, I digress. If I were you, I would learn Python. That is language that I started with several years ago for a reason. The syntax is simple, the language is robust, and it is pretty widely used.
To start with, you can look over the docs on be code’s built in Python functionality.
