abort controller

use controller.abort() to abort a fetch (mid call)

caveats

• can only be used once therefore,
• the abort controller should be created (new) and consumed in the same block / scope

refactor this below, should be a function that returns two functions

const [ fetch, abort ] = abortableFetch()

 
const App = () => {
  const [state, setState] = useState({})
 
  useEffect(() => {
    const controller = new AbortController()
 
    fetch("/some_url", {
      signal: controller.signal,
    })
      .then(res => res.json())
      .then(json => setState(json))
  
    return () => {
      controller.abort()
    }
  }, [])
 
  return (
    <div>
    </div>
  )
}
