How NOT to test custom React hooks (and how to test them)

It can be tempting to try and call your custom hook manually and test it that way, but you'll run into the error "Hooks can only be called inside the body of a function component." And for good reason. Let's talk about why that is and the proper way to test a custom React hook.

When I run my updated function (the setState returned from hook), I got a warning saying to wrap it in an `act method. Is there a reason that didn't show for you?

I couldn't understand the reason in changing the useCounter return type from array to object. How is that going to affect the return value when the value changes. Can anyone explain this ?
