03. Read Write File 👩‍🏫🧑‍🏫

// fs is a Node standard library package for reading and writing files
const fs = require('fs');

// Return the contents of 'data.csv' as a string in the variable "data"
// "utf8" encodes the raw buffer data in human-readable format
fs.readFile('data.csv', 'utf8', (error, data) =>
  error ? console.error(error) : console.log(data)
);

// Uncomment this next function to write to the file with anything you pass in as process.argv[2]

// fs.writeFile('log.txt', process.argv[2], (err) =>
//   err ? console.error(err) : console.log('Success!')
// );
