 This SDK builds upon the [JavaScript SDK](https://github.com/launchdarkly/js-client-sdk), supporting all of the same functionality, but using React's Context API to provide additional conveniences. While using this SDK you may need to directly interact with the underlying JavaScript SDK. For more information on how to use the JavaScript SDK and its characteristics, see the [SDK's README](https://github.com/launchdarkly/js-client-sdk/blob/main/README.md).
