text: /* ## MY FIRST I/O! (Exercise 3 of 13)
  
  Write a program that uses a single synchronous filesystem operation to
  read a file and print the number of newlines (\n) it contains to the
  console (stdout), similar to running cat file | wc -l.
  
  The full path to the file to read will be provided as the first
  command-line argument (i.e., process.argv[2]). You do not need to make
  your own test file. */
  const fs = require('fs')
  let buff = fs.readFileSync(process.argv[2])
  console.log(buff.toString().split('\n').length - 1)
