Example 1: v-bind Shorthand
<!-- full syntax -->
<a v-bind:href="url"> ... </a>
<!-- shorthand -->
<a :href="url"> ... </a>
<!-- shorthand with dynamic argument (2.6.0+) -->
<a :[key]="url"> ... </a>
Example 2: v-bind
<div v-bind:class="{ active: isActive }"></div>
The above syntax means the presence of the active class will be determined by the truthiness of the data property isActive.
