We also understand that the bar for adding a new primitive to React is extremely high. For curious readers, we have prepared a [detailed RFC](https://github.com/reactjs/rfcs/pull/68) that dives into motivation with more details, and provides extra perspective on the specific design decisions and related prior art.
**Crucially, Hooks work side-by-side with existing code so you can adopt them gradually.** We are sharing this experimental API to get early feedback from those in the community who are interested in shaping the future of React — and we will iterate on Hooks in the open.
Finally, there is no rush to migrate to Hooks. We recommend avoiding any "big rewrites", especially for existing, complex class components. It takes a bit of a mindshift to start "thinking in Hooks". In our experience, it's best to practice using Hooks in new and non-critical components first, and ensure that everybody on your team feels comfortable with them. After you give Hooks a try, please feel free to [send us feedback](https://github.com/facebook/react/issues/new), positive or negative.

We intend for Hooks to cover all existing use cases for classes, but **we will keep supporting class components for the foreseeable future.** At Facebook, we have tens of thousands of components written as classes, and we have absolutely no plans to rewrite them. Instead, we are starting to use Hooks in the new code side by side with classes.
