  • How to require the read and write methods from the Node filesystem promise module
  • Explain the path module’s __dirname argument
  • Understand how to use a JSON file as a database
  • Understand the purpose of using the filesystem promise module
  • Implement functions to read and write to the JSON file
  • Implement handler functions to invoke the read/write functions.
  • Understand the coding practice to create a separation of concerns between handler functions and module methods
  • Explain how to export functions through the use of the Node CommonJS system
  • Understand how to use exported functions in another file
