The tag is a crucial component when developing a single-page application using Vue.js and Vue Router. Its function is to render the route component that matches the current URL.
Specifically, when you define multiple routes in Vue Router and nest them within Vue components using the tag, Vue Router will match the current URL to the corresponding route and render the component associated with that route in the for display.
The benefit of doing this is that it allows for switching between pages without having to reload the entire page, thus improving the user experience. Additionally, using the tag, you can dynamically display different content and components on the same page, making users feel like they are navigating on the same page.
Here is a simple example demonstrating how to use the tag in Vue.
<template>
<div>
<router-view></router-view>
</div>
</template>
In this example, the tag is used to render the matched child route components in the parent component. As a result, when users visit different routes, Vue Router will automatically load and display the corresponding components based on the current URL.
In conclusion, the tag plays a vital role in Vue.js when combining with Vue Router for developing single-page applications, as it is used to dynamically render the content of the matched route components. I hope this explanation helps you understand the role of the tag.
