Components & Slots

Templates

Vue.js uses HTML-based template syntax to bind the Vue instance to the DOM, very useful for components.

 

Templates are optional, you can also write render functions with optional JSX support.

Components

A collection of elements that are encapsulated into a group that can be accessed through one single element.

<nav>
	<a href="">
    	<img src=""></img>
    </a>
    
    <ul>
    	<li></li>
        <li></li>
    </ul>    
</nav>
<navbar></navbar>
