I use JS a lot these days but it's not the first one I learned (it was the second). My first foray into programming was a combination of C++ and GameMaker Language. I wanted to make games when I grew up and I remember reading everywhere that C++ was the language to learn. I was also using GameMaker a lot after school to hack together terrible prototypes which, at the time, used GameMaker Language.
After reading through hundreds of pages of a introduction to C++ book, I still never really got the hang of C++ but some of that knowledge stuck around and helped out with JS and Python. Today I haven't written any C++ or GameMaker Language in years but I'm sure they helped me get to where I am now.
What was the first programming language you learned and why did you learn it? Did you have a choice or was it by necessity?
