I did some React development some years ago, and was glad to move away from it because of the ridiculous churn in the ecosystem. It was like building on top of quicksand. At the time, I thought it was because React was new, and new stuff tends to have churn because people are just figuring out the optimum patterns and false starts are to be expected. When I look into React years later, the churn is still going on, which perhaps is a warning sign it just wasn't well thought through to begin with, or that the ecosystem has been captured by architecture astronauts on a lifelong quest for some kind of pure ideal rather than usability and stability.
