Ask HN: How are you using LLMs to learn a new programming language?

Everyone seems to have that one project or to-do item that they're finally getting around to thanks to LLMs. Mine is learning how to program in C. I'm curious how folks are using LLMs to approach similar goals. Are you working on a project in the target language and having the LLM explain things as you go along? Are you writing small pieces of code and having the LLM explain why something should be done in one way but not another? What if you're using it to learn a new programming concept altogether, like functional programming patterns?
