I can use online tutorials and chatgpt to develop and deploy a full-stack web app. It’s quite easy but also annoying that I don’t understand what I am actually doing there. It’s a bit overwhelming, where to start? can you recommend something that helped you cover this broad field of knowledge?
Same for web apps. Build something to do something you want to do. Knowing enough to make something is enough to make something.
You will never know it all. Nobody even knows what "it all" is. Good luck.
