// No header guards since it is legitimately possible to include this file more
// than once with and without REACT_NATIVE_DEBUG.

// react_native_assert allows us to opt-in to specific asserts on Android and
// test before moving on. When all issues have been found, maybe we can use
// `UNDEBUG` flag to disable NDEBUG in debug builds on Android.

// Asserting is appropriate for conditions that:
//   1. May or may not be recoverable, and
//   2. imply there is a bug in React Native when violated.
// For recoverable conditions that can be violated by user mistake (e.g. JS
// code passes an unexpected prop value), consider react_native_expect instead.
