The ref attribute can be a callback function instead of a name. This callback will be executed immediately after the component is mounted. The referenced component will be passed in as a parameter, and the callback function may use the component immediately, or save the reference for future use (or both).
It then only gives an example of using the component immediately. I'm trying to find out how i would use this function to access the component immediately, and save the component for future use, as it says we are able to do.
To continue their specific
theInput example, how would i call
focus() on the input element, and save it to the
theInput key in refs?
Or put another way, how would i make the
console.log in this fiddle return an object with a
theInput key of the input element's component ref: https://jsfiddle.net/qo3p3fh1/1/
