What is the difference between asyncData and fetch in Nuxt.js?

In Nuxt.js, asyncData is used to fetch data before rendering a page, while fetch is used to fetch data after the component is created.

Can you explain when to use each of them?

Use asyncData when you need the data to be available before rendering the page, like for SEO purposes. Use fetch when you want to fetch data after the component is created, such as for client-side interactions.

Are there any performance differences between the two?

Yes, asyncData can improve performance for initial page loads since it fetches data server-side, while fetch may lead to a slower initial render as it fetches data client-side.

Can I use both in the same component?

Yes, you can use both asyncData and fetch in the same component, but be mindful of their purposes and impacts on performance.
