问题描述

在JavaScript中实现堆栈和队列的最佳方法是什么？

What is the best way to implement a Stack and a Queue in JavaScript?

我正在寻找分流码算法，我将要需要这些数据结构。

I'm looking to do the shunting-yard algorithm and I'm going to need these data-structures.

推荐答案

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
