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;
};

没有数组(年代)

//Javascript stack linked list data structure (no array)

function node(value, noderef) {
    this.value = value;
    this.next = noderef;
}
function stack() {
    this.push = function (value) {
        this.next = this.first;
        this.first = new node(value, this.next);
    }
    this.pop = function () {
        var popvalue = this.first.value;
        this.first = this.first.next;
        return popvalue;
    }
    this.hasnext = function () {
        return this.next != undefined;
    }
    this.isempty = function () {
        return this.first == undefined;
    }

}

//Javascript stack linked list data structure (no array)
function node(value, noderef) {
    this.value = value;
    this.next = undefined;
}
function queue() {
    this.enqueue = function (value) {
        this.oldlast = this.last;
        this.last = new node(value);
        if (this.isempty())
            this.first = this.last;
        else 
           this.oldlast.next = this.last;
    }
    this.dequeue = function () {
        var queuvalue = this.first.value;
        this.first = this.first.next;
        return queuvalue;
    }
    this.hasnext = function () {
        return this.first.next != undefined;
    }
    this.isempty = function () {
        return this.first == undefined;
    }

}

如果你理解栈的push()和pop()函数，那么queue只是在相反的意义上进行这些操作之一。push()的对边是unshift()， pop()的对边是shift()。 然后:

//classic stack
var stack = [];
stack.push("first"); // push inserts at the end
stack.push("second");
stack.push("last");
stack.pop(); //pop takes the "last" element

//One way to implement queue is to insert elements in the oposite sense than a stack
var queue = [];
queue.unshift("first"); //unshift inserts at the beginning
queue.unshift("second");
queue.unshift("last");
queue.pop(); //"first"

//other way to do queues is to take the elements in the oposite sense than stack
var queue = [];
queue.push("first"); //push, as in the stack inserts at the end
queue.push("second");
queue.push("last");
queue.shift(); //but shift takes the "first" element

如果有人需要它，你可以使用这个NPM包https://www.npmjs.com/package/data-structures-typescript，它有一个队列和堆栈，它支持javascript和typescript，它是通用的，所以你可以用你自己的值类型;)

使用两个堆栈构造一个队列。

O(1)用于入队和出队操作。

class Queue {
  constructor() {
    this.s1 = []; // in
    this.s2 = []; // out
  }

  enqueue(val) {
    this.s1.push(val);
  }

  dequeue() {
    if (this.s2.length === 0) {
      this._move();
    }

    return this.s2.pop(); // return undefined if empty
  }

  _move() {
    while (this.s1.length) {
      this.s2.push(this.s1.pop());
    }
  }
}

单端队列

这是一个使用映射的队列。由于插入顺序得到了保证，所以可以像迭代数组一样迭代它。除此之外，它的思想与Queue.js非常相似。

我做了一些简单的测试，但还没有进行广泛的测试。我还添加了一些我认为很好的功能(通过数组构造)或易于实现(例如last()和first())。

它背后的简单版本/直觉如下:

class Queue {
    constructor() {
        this.offset = 0
        this.data = new Map()
    }

    enqueue(item) {
        const current = this.offset + this.length()
        this.data.set(current, item)
    }

    dequeue() {
        if (this.length() > 0) {
            this.data.delete(this.offset)
            this.offset += 1
        }
    }

    first() {
        return this.data.get(this.offset)
    }

    last() {
        return this.data.get(this.offset + this.length() - 1)
    }

    length() {
        return this.data.size
    }
}

简单版本的问题是，当内存索引超过9千万亿(Number.MAX_SAFE_INTEGER的值)时，需要重新映射内存。此外，我认为它可能很好有数组构造，它很高兴看到值正在进入队列和退出队列返回。可以通过编写以下代码来解释这一点:

class Queue {
    constructor() {
        this.offset = 0
        this.data = new Map()
        if (arguments.length === 1) this._initializeFromArray(arguments[0])
    }

    enqueue(item) {
        const current = this.offset + this.length()
        this.data.set(current, item)
        let result = this.data.get(current)
        this._remapDataIfMaxMemoryViolation(current, Number.MAX_SAFE_INTEGER)
        return result
    }

    dequeue() {
        let result = undefined
        if (this.length() > 0) {
            result = this.data.get(this.offset)
            this.data.delete(this.offset)
            this.offset += 1
        }
        if (this.length() === 0) this.offset = 0
        return result
    }

    first() {
        return this.data.get(this.offset)
    }

    last() {
        return this.data.get(this.offset + this.length() - 1)
    }

    length() {
        return this.data.size
    }

    _remapDataIfMaxMemoryViolation(current, threshhold) {
        if (current+1 === threshhold) {
            const length = this.length()
            this.offset = 0
            for (const [key, value] of this.data) {
                this.data.set(this.offset, value)
                this.data.delete(key, value)
                this.offset += 1
                if (this.offset === length) break
            }       
        }
    }

    _initializeFromArray(array) {
        for (const value of array) {
            this.data.set(this.offset, value)
            this.offset += 1
        }
    }
}

我在Chrome开发控制台进行了一些测试，对完整版本进行了以下调用。

l = console.log // I'm lazy with typing
q = new Queue()
l('enqueue', q.enqueue(1))
l('enqueue', q.enqueue(2))
l('enqueue', q.enqueue(3))
l('enqueue', q.enqueue("hello"))
l('enqueue', q.enqueue("monkey"))
l('show 5 elements: ', q.data)
l('length', q.length())
l('first', q.first())
l('last', q.last())
l('dequeue', q.dequeue())
l('dequeue', q.dequeue())
l('show 3 elements', q.data)
q._remapDataIfMaxMemoryViolation(q.length()+q.offset-1, 5)
l('show 3 remapped elements', q.data)

l(queue = new Queue([3,4,5,6,7,8,9]))
l(queue.data)
