/* 初始化栈 */
// Javascript 没有内置的栈类,可以把 Array 当作栈来使用
const stack = [];
/* 元素入栈 */
stack.push(1);
stack.push(3);
stack.push(2);
stack.push(5);
stack.push(4);
/* 访问栈顶元素 */
peek = stack[stack.length - 1];
/* 元素出栈 */
pop = stack.pop();
/* 获取栈的长度 */
size = stack.length;
/* 判断是否为空 */
is_empty = stack.length === 0;
