<p dir="auto">for example in render function:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="const a = 'Hello world unReactivity'

export default {
render(c){
return c(div,[a])
}
}
"><pre class="notranslate"><code class="notranslate">const a = 'Hello world unReactivity'

export default {
render(c){
return c(div,[a])
}
}

</code></pre></div>
<p dir="auto">here the a is not a reactivity data,but when we use template,it seems that we must make a to be a reactivity data?sometimes is not in need.</p>
<h3 dir="auto">What does the proposed API look like?</h3>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="&lt;template&gt;
&lt;div&gt;
{{ a }}
&lt;/div&gt;
&lt;/template&gt;
&lt;script&gt;
export default {
unReactivity:{
a: 'Hello world unReactivity'
}
}
&lt;/script&gt;"><pre class="notranslate"><code class="notranslate">&lt;template&gt;
&lt;div&gt;
{{ a }}
&lt;/div&gt;
&lt;/template&gt;
&lt;script&gt;
export default {
unReactivity:{
a: 'Hello world unReactivity'
}
}
&lt;/script&gt;
</code></pre></div>

<p dir="auto">I think it would be nice to be able to have some sort of description or documentation index for the props. This index can than also be displayed in the vue devtools. I think it would help other users using already build components. For example when using a framework like vuetify so they don't have to go back to the documentation of what a prop does.</p>
