react-native-ab

Uses <Experiment> and <Variant> components to define tests directly in JSX, making setup intuitive and eliminating complex state management for basic UI experiments.

Provides onChoice and onRawChoice callbacks to easily send experiment data to services like Google Analytics, as shown in the README with console logging examples.

Offers methods like reset() and getActiveVariant() accessible via refs, allowing dynamic management such as resetting tests on user actions, demonstrated in the usage example.

Defaults to random variant selection using Math.random(), with a customizable choose prop for overriding with custom logic, keeping basic tests straightforward.
