Explanation
Vue.js Slots are a powerful feature that allows you to define the structure of a component from outside of the component. They provide a way to pass content from a parent component to a child component, and they can be used to define the structure of a component in a declarative way.
Use
Vue.js Slots are used to provide a flexible way to design reusable components. They provide a mechanism for a parent component to provide content to a child component in a way that allows the child component to render the content in a custom way. Slots can also be used to provide a default fallback content for a component.
Important Points
- A slot is a placeholder that can be filled with content by a parent component.
- Slots are defined using the
v-slotdirective. - The name of a slot is defined using the
nameattribute on theslotelement. - A slot can also be given a default value using the
slotattribute on an HTML element. - Slots can be used to create highly customizable components that can be reused across an application.
Summary
Vue.js Slots provide a powerful way to define the structure of a component from outside the component.

Understanding how to use slots effectively can greatly enhance the reusability and flexibility of your Vue.js components.
