Summary:
With the new architecture, this diagnostic utility will be helpful to ensure stronger validation of various corner cases at runtime, like handling an early JavaScript exception when loading React Native.
If `global.RN$DiagnosticFlags` is set to a string of comma-separated flags, the util functions will be able to perform additional diagnostics. For now, the accepted flags are:
- `early_js_errors`
- `all`
This is still experimental and may change frequently.
