/**

* Registers a child component with the parent component.
|
|
*
|
|
* @param id A unique key for the child component. If the `id` is `undefined`, the registration logic will not run (this can sometimes be the case during SSR).
|
|
* This can be either a value, or a function that generates a value based on already registered siblings' ids.
|
|
* If a function, it's called with the set of the ids of all the items that have already been registered.
|
|
* Return `existingKeys.size` if you want to use the index of the new item as the id.
|
|
* @param itemMetadata Arbitrary metadata to pass to the parent component. This should be a stable reference (for example a memoized object), to avoid unnecessary re-registrations.
|
|
*
|
|
* @ignore - internal hook.
