(1)、存储空间更大：IE8 下每个独立的存储空间为 10M，其他浏览器实现略
有不同，但都比 Cookie 要大很多。

(2)、存储内容不会发送到服务器：当设置了 Cookie 后，Cookie 的内容会随
着请求一并发送的服务器，这对于本地存储的数据是一种带宽浪费。而 Web
Storage 中的数据则仅仅是存在本地，不会与服务器发生任何交互。

(3)、更多丰富易用的接口：Web Storage 提供了一套更为丰富的接口，如
setItem,getItem,removeItem,clear 等,使得数据操作更为简便。cookie 需要自己封
装。

(4)、独立的存储空间：每个域（包括子域）有独立的存储空间，各个存储空
间是完全独立的，因此不会造成数据混乱。

Sending requests to the server along with them is a waste of bandwidth for locally stored data. And the Web
The data in Storage is stored locally and does not interact with the server.

(3) more rich and easy-to-use interfaces: Web Storage provides a set of richer interfaces, such as
SetItem, the getItem, removeItem, clear, etc., make the data operation more simple. Cookies need to be sealed by themselves
Loading.

It is completely independent, so there is no data clutter.
