var notesString = fs.readFileSync('notes-data.json');

Since this is the string version, we haven't passed it through the JSON.parse method. So, I can set notes (the variable we defined earlier in addNote function) equal to the return value from the JSON.parse method. Then JSON.parse will take the string from the file we read and it will parse it into an array; we could pass in notesString ...
