TS how can I this function write to a arrow function?

How can I write this generic function with a arrow function ?

function simpleState<T>(initial: T): [() => T, (v: T) => void] {
  let value: T = initial;
  return [
    () => value,
    (v: T) => {
      value = v;
    }
  ]
};

>Solution :

const simpleState = <T>(initial: T): [() => T, (v: T) => void] => {
  // same function body as before
}

Since you tagged react-native, be aware that in a .tsx file, this will probably not work, since the <T> will be parsed as being a JSX tag, but you can do it in a .ts file, then import it into a .tsx file.
