It's clear that React is the winning framework currently, with probably Angular and Vue following. I would not blame anyone looking to be employed as a frontend developer to go with React.

That's part of the problem and it's a vicious circle.

And most people like React and I can understand that. It's easy to use and understand. At least at first (debugging subtle (performance or not) bugs related to React's model is… not always easy but these bugs usually arrive when your app is already big enough. This is probably true of any framework).

What's more, most people are not that sensitive to performance and if they are, they might not be aware of React's problems before learning it and practicing (which is also true of any framework).

And also, nobody is fired for picking React.
