I've been coding for 40 years, it's both my job and my hobby, and I still feel old and out of touch when reading or taking part in coding conversations outside of my sphere :)

This is not meant to be discouraging - even the smallest amount of coding you could learn will be immensely rewarding - more to say that coding is vast arena with a breadth of complexity that can often feel overwhelming. So don't be put off when you teach yourself some JavaScript and then still feel adrift in a conversation about C#.

I don't have any specifics to recommend, but I would say that you should start small. Don't aim to write the next Flappy Bird as your first project, or the next Mastodon. Just concentrate on making a web page say "Hello world!" or changing the colour of some text. Back in the 80s, most kids got their first taste of programming by having a computer shop C64 print "Dave is rad!" on an infinite loop! :)

Good luck!
