A small node script for detecting if a word is a palindrome

pal.js

#!/usr/bin/env node

var word = process.argv.slice(2)[0]

if(!word) return console.error("Please call this script with a word, e.g.: \n node pal.js someword")

// split the word into letters
var letters = word.split('')
var i=0
var len = letters.length
var max = len-1
// iterate over each letter
for(i;i<len;i++){
  // if we've gotten to the middle of the word, they've all passed, and this is a palendrome.
  if(i >= len/2) return console.log("That word is a palindrome!")
  // if any letter does not match the same letter from the end of the word, this is not a palendrome
  if(letters[i] != letters[max-i]) return console.log("That word is not a palindrome.")
