The is prop and the special <component> tag #

In both versions, you can render a dynamically determined component or element by using this syntax:

<component is="div" >


<component is="myComponent" >

<component :is="DataContainingComponentOrString" >

But only in Vue 2, the is prop also works on normal elements:

<div is="span">

If you respect the restriction of Vue 3 that is only works on the special <component> tag, you're fine.
