Why do a in nextjs in Link?

Question

React

Hello. Question for those who code in Next.js. <Link>Is it necessary to do it inside <a>？ It is used with in the docks , but it is displayed normally in the markup and without And the second question, is it necessary to use the as attribute?

<Link href={'/'}><a>{post.title}</a></Link>

<a><a>

<Link href={`/post/[id]`} as={`/post/${post.id}`}>{post.title}</Link>

or can

<Link href={`/post/${post.id}`}>{post.title}</Link>

. It's just that the second option works dynamically for me, which is strange

Do not write a tag, but in the comments it is marked as Deprecated https://github.com/vercel/next.js/blob/feb10f45c10...
