After experiencing ad hoc inline scripts, frameworkless jQuery spaghetti code, inflexible monoliths like angular, and overly simplistic micro frameworks like backbone, I'm super happy with where we're at with react and react like frameworks. I really do feel like we've hit the sweet spot between power, simplicity, flexibility, and ease of use which is why I'm confident that things aren't going to be as volatile as the past. React is already 10 years old now and still going strong with no new trends looking to usurp it. I think those old trends were necessary experiments to get to where we are now, and I think the old meme of web dev changing every week is no longer true.
