                问题描述

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

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

                解决方案

                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
