Creating the Express Route Controller for the /words Route

First, you need to implement the route handler that will interact with the Word model to retrieve the words from MongoDB. Listing 29.16 implements the getWords() route handler for the /words route. This handler reads the limit, skip, sort, and direction parameters from the query and uses them to query the MongoDB database.

The getSortObj() function transforms the sort fields and direction into the sort object that will be used in the .sort() method on the Query object.
