// Component naming convention:
//
//  componentDisplayName - The React/JS-facing name (e.g. "Text").
//                         Accessed via Component.componentName in JS.
//  reactViewName        - The name React Native uses to identify the component
//                         (e.g. "RCTText"). This is what we use to identify
//                         the underlying React Native component name (it is the
//                         same as the native component name for most of third-party
//                         components (e.g. SVG) but is often different for built-in
//                         RN components (e.g. "RCTView").
//  nativeComponentName  - The Fabric/C++ component name (e.g. "Paragraph").
//                         Can be obtained on the C++ side by converting
//                         reactViewName via componentNameByReactViewName().
