What is the difference between the A tag and Link in Nextjs?

In Next.js, the main difference between the `` tag and the `Link` component is how they handle navigation between routes.

The `` tag is a standard HTML tag that performs a full page reload[1] when clicked, resulting in slower navigation and a loss of React and browser state^[1], such as scroll position or focused element^[1].

On the other hand, the `Link` component is a built-in component in Next.js^[1] that extends the `` tag to provide prefetching and client-side navigation between routes[1]. It is the primary way to navigate between routes in Next.js^[1]. When a `Link` component is clicked, it uses client-side rendering to only render the route segments that have changed, preserving React and browser state^[1] without reloading the entire page.

To use the `Link` component, you can import it from `next/link` and pass a `href` prop to specify the destination route. For dynamic segments, you can use template literals and interpolation to generate a list of links^[1].

Additionally, the `Link` component offers other optional props for customization, and you can also use the `useRouter` hook from `next/router` to programmatically change routes^[1].

Overall, the `Link` component in Next.js^[1] provides a more efficient and seamless navigation experience compared to a standard `` tag.

Please note that the above information is based on general knowledge of Next.js^[1] and may not cover every detail. For more specific and up-to-date information, it is recommended to refer to the official Next.js^[1] documentation.
