Wow, thanks for the link list! Will definitely take a look. Also create-react-app looks like exactly what I was looking for, very bare and to-the-point.
I had a lot of problems with front-end stuff as well. Turns out I didn't know Javascript well enough. Solved it by going through this course: http://watchandcode.com/p/practical-javascript
I've found the 'You Don't Know JS' series very helpful for understanding JS from the ground up. In book form or for free via !gh, https://github.com/getify/You-Dont-Know-JS.
You Don't Know JS has to be the best and most detailed book about JavaScript that exists. It might be a bit much for a beginner, so just skim it at first and come back when something doesn't make sense.
Nicolas Bevacqua's JavaScript Application Design: A Build First Approach isn't a bad place to start -- Manning has a few books on SPA design and development that are well-suited for experienced developers who are new to modern web front-end dev.
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.
