vue.jsHow do I create a "Hello World" application using Vue.js?

Creating a "Hello World" application using Vue.js is quite easy. Here is an example of the code you need to write:

<div id="app">
  {{ message }}
</div>

<script>
  new Vue({
    el: '#app',
    data: {
      message: 'Hello World!'
    }
  })
</script>

The output of this code will be:

Hello World!

This code consists of the following parts:

1. The HTML template: This is the <div> element with the id="app" attribute, inside which the {{ message }} expression is placed. This expression is used to output the value of the message data property.

2. The Vue instance: This is the new Vue() constructor function, which is used to create a new Vue instance. This instance is bound to the #app element and has a data property, which contains the message property with the value "Hello World!".

For more information on how to use Vue.js, please refer to the Vue.js documentation.
