Directions

1. Export helloMessage from messages/hello-message.js and import it into messages/say-message.js. If you run the messages/say-message.js file, you should see the following printed in the terminal:

   "Greetings! Let us begin!"
   

2. Export sayMessage from messages/say-message.js and import it into send-messages/say-hello-to.js. If you run the send-messages/say-hello-to.js file, you should see the following printed in the terminal:

   "Greetings! Let us begin!"
   "Hello Woody!"
   

3. Export sayHelloTo from send-messages/say-hello-to.js and import it into send-messages/give-message-to-mrs-potato.js. If you run the send-messages/give-message-to-mrs-potato.js file, you should see the following printed in the terminal:

   "Greetings! Let us begin!"
   "Hello Woody!"
   "Hello Mrs. Potato!"
   (Psst... Hi Buzz)
   

4. Run the index.js file. You should see an error in the terminal. Import or export from files until there are no more errors in the terminal. Once you successfully exported the necessary modules for the index.js file and imported them, you should see the following printed in the terminal:

   "Greetings! Let us begin!"
   "Hello Woody!"
   "Hello Mrs. Potato!"
   (Psst... Hi Buzz)
   "Hello Mr. Potato!"
   "Hello Mrs. Potato!"
   (Psst... You are looking very spudly today!)
   "Hello Mrs. Potato!"
   (Psst... There's a good deal on mattresses tomorrow.)
   "Hello Mrs. Potato!"
   (Psst... Do you like to do things in unnecessarily complicated ways?)
