Getting into React is kind of mixed bag. The core concepts are easy to understand and compared to other frameworks lean. JSX is easy, components are trivial but once you try to get productive, wow, it's not that simple anymore. It's more than a bit of HTML embedded in JS. So, you need really to spend time to understand the core of React very, very well. And this takes time, effort and at least a couple of real and serious apps you should write to understand why React and its concept are the next step in FE dev and why others use React's concept as blueprint (e.g. Inferno). Tutorials are not enough, real projects are the best way to grok React. I don't think it's like Java Swing, not at all (I think the comparison is misleading since React is from the ground very different, e.g. totally different design patterns/paradigms, .g. no observer pattern, and a super minimal API). It's a tool which is super flexible. It's definitely not your daddy's jQuery-based front-end framework which let you start quickly. But once you get more experienced with React you face much better code maintainability with a small code base already. Further, you should be good at JS and ES6. I guess this might be another obstacle for many. Compared to Vue which I like a lot and which shares also some similarities, Vue is more complex due to a large API surface, code-in-HTML templating syntax, nested instance semantics, observable gotchas, ES5 workarounds and a larger documentation that is absolutely vital to read and understand. Give React a try. You need of course a real use case. Many website's use cases don't require React and could be done with some simple server-side rendering. So, React is def not the best tool of every job. I was ignoring React too long by just using it for some toy projects or going through tutorials. This was not enough. Once I tried React for a real project, I learned its brilliance and I don't want to go back to anything else for SPAs or websites with more interactivity.
