Thank you for the answer, Dan. Would you also be able to clarify why Facebook uses an alpha version of React in production?

  We develop React and test it on Facebook before making open source releases. In most cases, we update the version that Facebook is using every few weeks. Since they aren't full releases at that point, we call them alphas. They let us get a better appreciation for the issues that the new code may have and how hard it is to update before we make everyone in the community upgrade.

    Isn't it semantically wrong to call it alpha if it is being used in production in one of the most used websites in the world? https://en.wikipedia.org/wiki/Software_release_life_cycle https://en.wikipedia.org/wiki/Software_release_life_cycle
