About JavaScript
This page is some interview questions about JavaScript.
The main useData() API can be used to access site, theme, and page data for the current page. It works in both .md and .vue files:
md
<script setup>
import { useData } from 'vitepress'
const { theme, page, frontmatter } = useData()
</script>
## Results
### Theme Data
<pre>{{ theme }}</pre>
### Page Data
<pre>{{ page }}</pre>
### Page Frontmatter
<pre>{{ frontmatter }}</pre>Results
