1. 每日一句分享:

   为了利用多核CPU的计算能力，HTML5提出Web Worker标准，允许JavaScript脚本创建多个线程，但是子线程完全受主线程控制，且不得操作DOM。所以，这个新标准并没有改变JavaScript单线程的本质。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://thinking.406sys.top/archives/2020/12/14.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
