Given that browsers, Node, and JavaScript are all rapidly evolving, lots of churn in the library and framework space is what I'd expect to see happening, and I'd argue should happen. The problem is bigger than just the rate of churn. It's that at the same time there are lots of newcomers into the field and they don't have time to sit down and thoroughly learn the tech from the ground up. Instead, they're thrown into a JR development role and told to swim or sink. Many do swim and learn the tech in the process, but only by "weathering the storm" so to speak.
