TypeScript Challenge!

I don't like this example to introduce generics, because it doesn't utilize the generic at all. Using
`function { getDescription(): string }[]): string { ... }`
has the same effect and doesn't need a generic.

I think TSLint or strict mode compilation will prevent this from happening. But retrofitting that into an existing long term project is a real time hole.

I saw the error right away! Yay for knowing something in typescript!
Great video!

Why do you need a generic if you'll get just a plain string back? 😅
