What is a slot in Vue? What is it used for?

Slot in Vue is a special place in a component where arbitrary content from the parent component can be inserted. This allows creating more versatile and reusable components that can display different content depending on the context.

Example of using slot:

<!-- MyButton.vue component -->
<template>
  <button>
    <slot>Click me</slot> <!-- If no content is provided, "Click me" will be shown -->
  </button>
</template>

<!-- Using the component -->
<MyButton>Send</MyButton> <!-- The text "Send" will be inserted into the button -->
