TypeScript Examples

Would be nice to have examples in the README for using types with Hookable e.g.

import { createHooks } from 'hookable';

export type HookTypes = {
  hello: (value: string) => void;
  ping: (value: string) => string;
};

// Create a hookable instance
const hooks = createHooks<HookTypes>();

// Hook on 'hello'
hooks.hook('hello', (val: string) => console.log(val));

// Call 'hello' hook and pass 'Hello World!'
hooks.callHook('hello', 'Hello World!');

// Hook on 'ping' that returns 'PONG'
hooks.hook('ping', (val: string) => {
  console.log(val);
  return 'PONG';
});

// Call 'ping' hook and pass 'PING'
hooks.callHook('ping', 'PING').then((val) => {
  console.log(val);
});

However I ran into an unexpected issue with the return type... if I set the type to the following it works without errors. But surely I need to specify the return type here right?

ping: (value: string) => void

Argument of type '(val: string) => string' is not assignable to parameter of type 'never'.(2345)

Start by reviewing the README and reproducing the reported behavior in the linked StackBlitz TypeScript example. Compare the documented Hookable type examples with the reported return-type error, then verify that the README presents accurate usage and that the example's expected typing behavior is clear.
