I have the following function in TS, I would like to rewrite it to an arrow function.

I tried with no result. Could you please point me the right direction? Thanks!

function log<T>(message: T): IO<void> {
  return new IO(() => console.log(message));
}

Your attempt was close, but you forgot to include the generic argument declaration in front of the arrow function parameters. Try something like this: 

const log = <T>(message: T): IO<void> =>
   new IO(() => console.log(message));

If you're working in a .tsx file, you may need to do something a little more complex to make it work.

You could try to use:

const log = <T>(message: T): IO<void> => new IO(() => console.log(message));
