Write a Node.js script that takes a command line argument for a filename, then uses fs.readFile and fs.writeFile to produce a copy of the file in which all of the lines have been reversed and the additional extension .reverse has been added. Here is what usage looks like: // in foo.txt a b c d

// at the CLI: $:> node reverse_file.js foo.txt $:> ls foo.txt foo.txt.reverse $:> cat foo.txt.reverse d c b a try your best to do this challenge from memory! Bonus points if you can write it by hand first with completely valid syntax.
