/**
 * This Node.js script fetches data from the Star Wars API (SWAPI) and logs the name of each character in a specific film.
 *
 * It uses the 'request' module to make HTTP requests.
 *
 * The script expects the film ID as a command line argument (process.argv[2]).
 *
 * The 'request.get' function is used to make a GET request to the SWAPI for the film data. It takes two arguments:
 * 1. The URL, which includes the film ID
 * 2. A callback function that is called when the HTTP request is complete.
 *
 * The callback function parses the response body as JSON, iterates over the characters, and calls the 'logCharacterName' function for each character URL.
 *
 * The 'logCharacterName' function makes another GET request to the SWAPI for the character data and logs the character's name to the console.
