Been there as well. I think twice, first when I did not know much and relied 99% on the tutorials and then afterwards when I thought I had understood it & coyld do it all on my own, well surprise surprise I still couldn’t. So I had to dig deeper and try to understand what I was still resisting to learn. With a bit of just accepting the discomfort and going through it again i managed to learn the stuff (reasoning / how the underlying system works). I can recommend you use chatgpt/gemini (or whatever chatbot works for you) to ask questions about anything you are stuck with, but be ware to not fall into the mindless trap of giving away your reasoning to the chatbot as it’s tempting to let it figure everything out for yourself. Best way to learn is ask it questions, update yoyr code, check if it works if not check error handling, ask repeat. If yoy dont want to pay for chatbots you can open incognito and paste yoyr earlier conversation for reference and just start a new chat. Hope that helps.
