有很多方法可以在Javascript中实现堆栈和队列。上面的大多数答案都是非常肤浅的实现，我将尝试实现一些更可读(使用es6的新语法特性)和更健壮的东西。

下面是堆栈实现:

class Stack {
  constructor(...items){
    this._items = []

    if(items.length>0)
      items.forEach(item => this._items.push(item) )

  }

  push(...items){
    //push item to the stack
     items.forEach(item => this._items.push(item) )
     return this._items;

  }

  pop(count=0){
    //pull out the topmost item (last item) from stack
    if(count===0)
      return this._items.pop()
     else
       return this._items.splice( -count, count )
  }

  peek(){
    // see what's the last item in stack
    return this._items[this._items.length-1]
  }

  size(){
    //no. of items in stack
    return this._items.length
  }

  isEmpty(){
    // return whether the stack is empty or not
    return this._items.length==0
  }

  toArray(){
    return this._items;
  }
}

下面是如何使用堆栈:

let my_stack = new Stack(1,24,4);
// [1, 24, 4]
my_stack.push(23)
//[1, 24, 4, 23]
my_stack.push(1,2,342);
//[1, 24, 4, 23, 1, 2, 342]
my_stack.pop();
//[1, 24, 4, 23, 1, 2]
my_stack.pop(3)
//[1, 24, 4]
my_stack.isEmpty()
// false
my_stack.size();
//3

下面是es6中队列实现的代码:

class Queue{
 constructor(...items){
   //initialize the items in queue
   this._items = []
   // enqueuing the items passed to the constructor
   this.enqueue(...items)
 }

  enqueue(...items){
    //push items into the queue
    items.forEach( item => this._items.push(item) )
    return this._items;
  }

  dequeue(count=1){
    //pull out the first item from the queue
    this._items.splice(0,count);
    return this._items;
  }

  peek(){
    //peek at the first item from the queue
    return this._items[0]
  }

  size(){
    //get the length of queue
    return this._items.length
  }

  isEmpty(){
    //find whether the queue is empty or no
    return this._items.length===0
  }
}

下面是如何使用这个实现:

let my_queue = new Queue(1,24,4);
// [1, 24, 4]
my_queue.enqueue(23)
//[1, 24, 4, 23]
my_queue.enqueue(1,2,342);
//[1, 24, 4, 23, 1, 2, 342]
my_queue.dequeue();
//[24, 4, 23, 1, 2, 342]
my_queue.dequeue(3)
//[1, 2, 342]
my_queue.isEmpty()
// false
my_queue.size();
//3

要完整地了解如何实现这些数据结构以及如何进一步改进这些数据结构，您可能需要阅读jschap.com上的“在javascript中处理数据结构”系列。这是队列的链接——http://jschap.com/playing-data-structures-javascript-queues/

如果你想创建自己的数据结构，你可以创建自己的:

var Stack = function(){
  this.top = null;
  this.size = 0;
};

var Node = function(data){
  this.data = data;
  this.previous = null;
};

Stack.prototype.push = function(data) {
  var node = new Node(data);

  node.previous = this.top;
  this.top = node;
  this.size += 1;
  return this.top;
};

Stack.prototype.pop = function() {
  temp = this.top;
  this.top = this.top.previous;
  this.size -= 1;
  return temp;
};

对于队列:

var Queue = function() {
  this.first = null;
  this.size = 0;
};

var Node = function(data) {
  this.data = data;
  this.next = null;
};

Queue.prototype.enqueue = function(data) {
  var node = new Node(data);

  if (!this.first){
    this.first = node;
  } else {
    n = this.first;
    while (n.next) {
      n = n.next;
    }
    n.next = node;
  }

  this.size += 1;
  return node;
};

Queue.prototype.dequeue = function() {
  temp = this.first;
  this.first = this.first.next;
  this.size -= 1;
  return temp;
};

我认为实现堆栈和队列的最干净的方法应该是使用一个允许从两端添加和删除的容器，然后限制其在一端的功能，这可以通过Javascript中的一个简单数组来完成。

//堆栈容器在封装时使用的语句

// Allow push and pop from the same end
array.push(element);
array.pop();

//封装时在队列容器中使用的语句

// Allow push and pop from different ends
array.push(element);
array.shift();

var stack = [];
stack.push(2);       // stack is now [2]
stack.push(5);       // stack is now [2, 5]
var i = stack.pop(); // stack is now [2]
alert(i);            // displays 5

var queue = [];
queue.push(2);         // queue is now [2]
queue.push(5);         // queue is now [2, 5]
var i = queue.shift(); // queue is now [5]
alert(i);              // displays 2

摘自“9个你可能不知道的JavaScript技巧”

数组。

栈:

var stack = [];

//put value on top of stack
stack.push(1);

//remove value from top of stack
var value = stack.pop();

队列:

var queue = [];

//put value on end of queue
queue.push(1);

//Take first value from queue
var value = queue.shift();

  var x = 10; 
  var y = 11; 
  var Queue = new Array();
  Queue.unshift(x);
  Queue.unshift(y);

  console.log(Queue)
  // Output [11, 10]

  Queue.pop()
  console.log(Queue)
  // Output [11]
