The tutorials look good, but I already have a base knowledge of JS and frontend- just looking to begin making SPAs and using React or Vue, which I can't seem to get a grip on. There's so many loose components in them it's overwhelming :(
Ah, thought you might be referring to actually writing component-based logic and UIs.
Yeah, React is very much a pick-and-choose-for-your-own-situation kind of a tool. Somewhat true for Vue also. This is both a strength and a weakness, somewhat depending on how much you like to be in control of exactly what pieces you're using.
