vue check if list is empty

To check if a list is empty in Vue, you can use the v-if directive along with the length property of the list. Here are the steps to do so:

1. Start by defining your list in the Vue instance data. For example, you can create an empty list called myList:

data() {
  return {
    myList: []
  }
}

1. In your template, use the v-if directive to conditionally render content based on whether the list is empty or not. For example, you can display a message if the list is empty:

<div v-if="myList.length === 0">
  <p>The list is empty.</p>
</div>

1. If you want to display content when the list is not empty, you can use the v-else directive:

<div v-else>
  <p>The list is not empty.</p>
</div>

1. Optionally, you can also use the v-show directive instead of v-if if you want to toggle the visibility of the content based on the list's emptiness. The difference is that v-show will only toggle the CSS display property, while v-if will add or remove the element from the DOM:

<div v-show="myList.length === 0">
  <p>The list is empty.</p>
</div>

And that's how you can check if a list is empty in Vue using the v-if directive and the length property.
