What are Vue.js slots and how do they enhance components?

Slots in Vue.js provide a powerful mechanism for creating flexible and reusable components by allowing you to pass content from a parent component to a child component.

To use slots, define a slot element in your child component. This allows you to insert custom content when the component is used.

<template>
  <div>
    <slot></slot>
  </div>
</template>

Then, in the parent component, you can specify the content you want to insert:

<ChildComponent>
  <h1>Hello from parent!</h1>
</ChildComponent>

This will render <h1>Hello from parent!</h1> inside the <slot> in the child component. Slots enhance flexibility and allow for more dynamic component designs.
