1、能够嵌入动态文本于HTML页面。2、对浏览器事件做出响应。3、读写HTML元素。4、在数据被提交到服务器之前验证数据。5、检测访客的浏览器信息。6、控制cookies，包括创建和修改等。7、基于Node.js技术进行服务器端编程。

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
margin: 0;
padding: 0;
margin-left: 10px;
}
li{
list-style: none;
}
.add,.reduce{
display: inline-block;
width: 20px;
height: 20px;
border: 1px solid #000;
text-align: center;

.line{
border-bottom: 1px solid #000;
