const useMeaningOfLife = () => 42
const Message = (props: {meaningOfLife: number}) => {
  return <div>{props.meaningOfLife}</div>
}
 
const withMeaningOfLife = withHook('meaningOfLife', useMeaningOfLife)
const WrappedMessage = withMeaningOfLife(Message)
 
// displays 42
<WrappedMessage />

// usage for hooks with parameters
 
const useGreeting = (name: string) => `Hello, ${name}!`
const Message = (props: {name: string, greeting: string}) => {
  return <div>{props.greeting}</div>
}

const WrappedMessage = withMeaningOfLife(Message, props => [props.name])
 
// displays Hello, John!
<WrappedMessage name="John"/>

Returned HOC

withHook returns a higher order component that takes the following parameters:
