After building your component, you may find yourself wanting to "reach out" and invoke methods on component instances returned from `render()`. In most cases, this should be unnecessary because the reactive data flow always ensures that the most recent props are sent to each child that is output from `render()`. However, there are a few cases where it still might be necessary or beneficial, so React provides an escape hatch known as `refs`. These `refs` (references) are especially useful when you need to: find the DOM markup rendered by a component (for instance, to position it absolutely), use React components in a larger non-React application, or transition your existing codebase to React.
