Compound Components Validation

👨‍💼 Change to this (temporarily):
import { ToggleButton } from './toggle'

export const App = () => <ToggleButton />
Why doesn't that work (it's not supposed to, but can you explain why)? Can you figure out a way to give the developer a better error message that explains what they're doing wrong and how to fix it?
🚨 The tests will tell you in the message for the error you must throw when the context is undefined.
🦺 Additionally, this is where we can make TypeScript happier (TypeScript knew about the problem we'd run into in this step of the exercise!). Remember, TypeScript isn't making your life terrible. It's just showing you how terrible your life already is 😂 In this exercise, we're going to make our lives better.
(You can go ahead and undo the change to if you'd like. The tests will let you know that you've gotten it right).
