Documentation request
Please document how to use forwardRef (the preferred way) to retrieve a list or array of items. For example,
const foo = React.forwardRef( (props,ref) =>
props.superHeros.map(
( hero, index) => <li ref={ ref } key={ index }>{ hero }</li>
)

Perhaps the key question here is, why not do this?
Suppose there are 50,000
className='foo'elements that are returned by an embedded component. Is this code not portable? Is this code slower than having 50,000refcreated?Please document this.
Could you please file this in https://github.com/reactjs/reactjs.org? That’s the documentation repo.
Done
