Answer 1

Worker和SharedWorker的工作流程如下。工人和共用工作之间

Difference between Worker and SharedWorker

类似的特征。

The Worker works in another thread. So it's not affecting the main thread. So that time users can scroll, view the page without blocking. 

1. Worker can't access DOM elements from the web page. 
2. Worker can't access global variables and functions from the web page. 
3. Worker can't call alert() function. 
4. Objects such as window, parent, document can't be accessed inside the worker. 

工人自己的功能。

Workers life time between page creates and closure. Once the page creates the new workers will be created. View first image that blog diagram says about Wokers. 

共享工作者自己的功能。

共享工作者连接来自同一个域的所有网页。查看博客图表中关于Wokers vs Shared Workers的第二张图片。
