Styling: If you don't want to type the handler functions twice

[Joepock123]

Styling: If you don't want to re-write all of your handler variables twice in the server.js file you can import the module and in the route write server.get("/books/non-fiction", books-handler.getAllNonFictionHandler);

Destructuring is cool but not sure how it adds value here? DRY BABY!
