In this chapter, we were able to reuse the utility functions that we already made in previous chapters, making the process of filling out a remove note that much easier. Inside app.js, we worked on how the removeNote function is executed, if it was executed successfully, we print a message; if it didn't, we print a different message.
Next, we were able to successfully fill out the read command and we also created a really cool utility function that we can take advantage of in multiple places. This keeps our code DRY and prevents us from having the same code in multiple places inside of our application.
Then we discussed a quick introduction to debugging. Essentially, debugging is a process that lets you stop the program at any point in time and play around with the program as it exists at that moment. That means you can play around with variables that exist, or functions...
