Im on a project thats replacing react because of this issue. I don't agree with that descision, but lawyers.
We're going with Inferno. Vue feels like a better Angular, not a better React. It's not even comparable to React. It's just too clunky.
One pleasant surprise in this Facebook purge has been the discovery of seamless-immutable. It's far easier to work with, especially if you're using Typescript, which makes Immutable an absolute pain.
