What is a named slot in Vue and why use it?

A named slot lets you define multiple slots with different names inside a component. The parent can then send different content to each named slot, making the component more organized and flexible.

What is a scoped slot in Vue?

A scoped slot allows the child component to pass data back to the parent through the slot. The parent can then use this data inside the slot content, making the slot dynamic and interactive.
