React hook to scroll chat feed

Used in 100ms and many of my Chat applications.

import React from 'react'

function useChatScroll<T>(dep: T): React.MutableRefObject<HTMLDivElement> {
  const ref = React.useRef<HTMLDivElement>();
  React.useEffect(() => {
    if (ref.current) {
      ref.current.scrollTop = ref.current.scrollHeight;
    }
  }, [dep]);
  return ref;
}
