Ask HN: What are you learning in 2021

Not so much a new years resolution list but what are you planning to learn next year?

Most of mine are programming language related, most of which I probably won't get to but I would like to learn the basics of:

* APL or J

* Lisp

* Forth

* Lua

* JavaScript

And on programming topic, I would like to learn about parsing, tokenization, and the like. Not full compiler stuff but strategies for parsing markup/serialisation schemes.
