Vue.js is a popular JavaScript framework that helps us quickly build user interfaces. It's easy to learn and has extensive documentation and community support. If you want to learn Vue.js and start building applications with it, this article will give you some guidelines to get started.

1. Preparation

Before starting Vue.js, you need to make sure that your development environment can support it. First, you need a text editor, such as Sublime Text, Visual Studio Code, or Atom. Secondly, you need to install Node.js and npm (Node.js comes with npm). You can download Node.js and npm through the Node.js official website. Finally, you need to use Vue.js in your project, which you can install via: 

npm install vue

2. Writing your first Vue application

Now we are ready to build our The first Vue.js application. Open your text editor, create an HTML file and add the following code to the 93f0f5c25f18dab9d176bd4f6de5d30e tag: 

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

This will import the Vue.js library into your HTML document. Next, within the 6c04bd5ca3fcae76e30b72ad730ca86d tag, create a new dc6dce4a544fdca2df29d5ac0ea9906b element and identify it as the root element of the Vue application: 

<body>
  <div id="app">
  </div>
</body>

Now, we have our Vue application ready basic structure. Next, we'll create a Vue.js instance and link it to our root element. In the 3f1c4e4b6b16bbbd69b2ee476dc4f83a tag we added earlier, we write the following code: 

var app = new Vue({
  el: '#app'
})

This will create a new Vue.js instance and connect it to the element with 'id="app"'. This means that all Vue.js data and logic will be bound to this element.

3. Add data

Vue.js is a data-driven framework, which means that it basically builds the user interface by processing data. In order to start adding data, we need to use the "data" option of Vue.js. In the Vue.js instance added previously, we write the following code: 

var app = new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  }
})

In the above code, we added a "data" option and created a property called "message" and Set its value to "Hello Vue!". We can use this property to display data in our application.

4. Display Data

Now that we have added the data, we need to make sure it displays correctly in our application. For this, we can use Vue.js’s two-way data binding. In the dc6dce4a544fdca2df29d5ac0ea9906b element we created earlier, we add the following code: 

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

This will add a "{{ message }}" expression to our application and bind it to The "message" property in Vue.js instances. This means that when we change the value of the "message" property, the expression will automatically update.

5. Adding Events

Now that we understand how to add data and display it in the application, we can add some interactive functionality. To do this, we need to use the "methods" option of Vue.js. In the Vue.js instance we created earlier, we add the following code: 

var app = new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  },
  methods: {
    changeMessage: function () {
      this.message = 'Vue is awesome!'
    }
  }
})

In the above code, we added a "methods" option and created a method called "changeMessage". When this method is triggered, it will update the value of the "message" property. Now we will add a button and bind it to this method. In the dc6dce4a544fdca2df29d5ac0ea9906b element we created earlier, we add the following code: 

<div id="app">
  {{ message }}
  <button @click="changeMessage()">Change message</button>
</div>

This will add a button to our application that will trigger the "changeMessage" method when clicked.

6. Summary

So far, we have learned how to start using Vue.js and created a simple application. By using Vue.js' "data", "methods" and two-way data binding, we can easily display and change data. With Vue.js’ numerous options, we can easily extend our application and add more interactive features. Always remember: Vue.js is easy to learn and has extensive documentation and community support. So try starting building your own Vue.js application!
