For me, knowing how to code is based on fundamentals like understanding logic (in js, for example, function strings). When I was learning to code I learnt to speak English on my own, and then conversations helped me. Throughout my apprenticeships I've noticed that code requires understanding, because typing lines without knowing, or asking an AI to do it for you rather than explaining how to write it yourself is not ok. I use Claude. Every day I use it as a revision assistant! Removing code comments that I'd put in to structure myself, or testing a rendering with bootstrap, css, rather than tailwind. Once you understand the code, you'll know how to write it. Think of this sentence, and you'll know what I mean ;)
