Stack of js

function Stack() { this.dataStore = []; //存储栈元素}Stack.prototype = { constructor: Stack, push: function(element) {  this.dataStore.push(element) }, pop: function() {  return this.dataStore.pop() }, peek: function() {  return this.dataStore[this.dataStore.length - 1]; }, length: function() {  return this.dataStore.length; }, clear: function() {  this.dataStore.length = 0; }};//转换进制function mulBase(num, base) { var s = new Stack(); do {  s.push(num % base);  num = Math.floor(num /= base); } while (num > 0); var converted = ""; while (s.length() > 0) {  converted += s.pop(); } return converted;}var num = 125;var base = 8;//125转8进制var newNum = mulBase(num, base);console.log(num + " converted to base " + base + " is " + newNum);//验证回文串function isPalindrome(word) { var s = new Stack(); for (var i = 0; i < word.length; ++i) {  s.push(word[i]); } var rword = ""; while (s.length() > 0) {  rword += s.pop(); } if (word == rword) {  return true; } else {  return false; }}var word = "ollo";if (isPalindrome(word)) { console.log(word + " is a palindrome.");} else { console.log(word + " is not a palindrome.");}
