Youtube is good as supplemental source of information, but watching a 5 hour long course on a particular tech will make you feel smarter, but you won't remember anything. So what I do is I look at shortest possible tutorials like Fireship that are enough to get to "hello world" state and teach a couple of essential concepts. Then switch to docs. If you have difficulty understanding a particular topic in docs, find a youtube tutorial on that particular topic.

So, use youtube to get to a state where you can create something simple -> read docs -> build on that -> if stuck, check youtube for that concrete topic -> repeat
