Everyone knows that React is one of the most popular JavaScript libraries for building user interfaces — and many users of React choose it because they think it’s supported by Facebook. But is it really? That depends on what you mean by React, and what you mean by support. Keenan Szulik writes on the Tidelift blog:

Since its release in 2013, React has grown into a proper open source phenomenon … with more than 100,000 GitHub stars, over 300,000 dependent repositories, and more than 800 contributors.

Facebook’s contributions to React and the JavaScript ecosystem around it are truly epic — the stuff of legend. But when we dive into the dependencies of the default create-react-app, only 24 of the 1,103 packages come from repositories in Facebook’s GitHub organizations. That’s less than 3% of the dependencies required to build the “Hello, World” app with create-react-app!

So who supports React?
