 #### Turbo Native Modules
 
-JavaScript spec files **must** be named `Native<MODULE_NAME>.js` and they export a `TurboModuleRegistry` `Spec` object. The name convention is important because the Codegen process looks for modules whose `js` (`jsx`, `ts`, or `tsx`) spec file starts with the keyword `Native`.

 ### Supported Types
 
-When using Flow or TypeScript, you will be using [type annotations](https://flow.org/en/docs/types/) to define your spec. Keeping in mind that the goal of defining a JavaScript spec is to ensure the generated native interface code is type safe, the set of supported types will be those that can be mapped one-to-one to a corresponding type on the native platform.

 ### Be Consistent Across Platforms and Eliminate Type Ambiguity

 ## Preparing your JavaScript Codebase for the new React Native Renderer (Fabric)
 
 The new renderer, Fabric, doesn’t use the UIManager, so direct calls to UIManager will need to be migrated. Historically, calls to UIManager had some pretty complicated patterns. Fortunately, we’ve created new APIs that are much cleaner. These new APIs are forward compatible with Fabric, so you can migrate your code today, and the APIs will work properly when you turn on Fabric!
 
-Fabric will be providing new type safe JS APIs that are much more ergonomic than some of the patterns we've seen in product code today. These APIs require references to the underlying component, no longer using the result of `findNodeHandle`. `findNodeHandle` is used to search the tree for a native component given a class instance. This was breaking the React abstraction model. `findNodeHandle` is not compatible with React 18. Deprecation of `findNodeHandle` in React Native is similar to the [deprecation of `findDOMNode` in React DOM](https://reactjs.org/docs/strict-mode.html#warning-about-deprecated-finddomnode-usage).

 ### Migrating `findNodeHandle` / getting a `HostComponent`

 We can’t convert this call to `this._ref.measure` because `this._ref` is an instance to `ChildComponent`, which is not a HostComponent and thus does not have a `measure` function.
 
-`ChildComponent` renders a `View`, which is a HostComponent, so we need to get a reference to `View` instead. There are typically two approaches to get what we need. If the component we need to get the ref from is a function component, using `forwardRef` is probably the right choice.

 Be wary of your assumptions, as uncaught subtleties can introduce differences in behavior! It’s a good idea to have snapshot tests of your component as they will highlight any differences pre and post your migration.
