Why is there so much hype around React.js?
Yes, typically people argue with Facebook as a big backer and the nowadays tremendous ecosystem. But a big part of this ecosystem for example tries to solve problems that only exist because of React. The way it works seems to be completely contrary to existing web technologies, so that more and more convenience libraries are written to make things work in React, that already would work without it. React is also neither the fastest nor the most convenient way to do componented web applications. It's speedy but also not the fastest in rendering.
So what's it that draws people to it?
