palindrome

var letters = [];
var word = "racecar"  //bob

var rword = "";

//put letters of word into stack
for (var i = 0; i < word.length; i++) {
    letters.push(word[i]);
}

//pop off the stack in reverse order
for (var i = 0; i < word.length; i++) {
    rword += letters.pop();
}

if (rword === word) {
    console.log("The word is a palindrome");
}
else {
    console.log("The word is not a palindrome");
