Let's say there is a button, by clicking on which a popup will open. How to get to the popup in React if it is three nine lands away from the button and in a completely different component tree?
Refs? JS selectors?

Describe a little more what you want to do. How does a popup open - does it just have an "open"/"closed" property, or is it a method that needs to be called? In a good way, the state of this popup descends from top to bottom through `props`.
To avoid building long ladders of props, check out Context in React.
If querySelector() is needed - i.e. get the DOM element itself - i.e. ReactDOM.findDOMNode() .
