A function that merges React refs into one. Filters out invalid (eg. falsy) refs as well and returns original ref if only one valid ref was given.

• Install by executing npm install merge-refs or yarn add merge-refs.
• Import by adding import mergeRefs from 'merge-refs'.
• Use it in ref like so: <div ref={mergeRefs(ref, someOtherRef)} />

• Refs created using createRef()
• Refs created using useRef()
• Functional refs

function Hello() {
  const ref1 = useRef<HTMLDivElement>(); // I'm going to be updated!
  const ref2 = (element: HTMLDivElement) => {
    // I'm going to be called!
  };

  return <div ref={mergeRefs(ref1, ref2)} />;
}
