Summary  
This chapter covers implementing two-way data binding between reactive state and input elements using a directive, keeping UI and data in sync automatically.

General domain of usage  
Form input handling



Vue allows you to connect input fields directly to reactive data using the `v-model` directive. This creates a two-way binding between the input and the data.

```vue 
<script setup>
import { ref } from "vue";

const name = ref("");
</script>

<template>
  <input v-model="name" placeholder="Enter your name" />
  <p>{{ name }}</p>
</template>
```

When the user types in the input field, the value of `name` updates automatically. When the value changes in JavaScript, the input field also updates.

This two-way connection keeps the UI and data in sync without manual event handling.

`v-model` is commonly used in forms to collect and manage user input.


Build dynamic interfaces using Vue.js and modern JavaScript. Render data, handle user interactions, structure components, and manage state in a clear and scalable way.

Understand what Vue.js is and how it simplifies building interactive interfaces. Set up a Vue project using Vite and explore how files and components are organized.

Render dynamic data using template syntax and build reactive interfaces with Vue. Handle user events, apply conditions, and display lists based on data.

Break interfaces into reusable components and organize UI structure. Pass data between components and communicate using props and events.

Manage application state using reactive data structures. Derive values with computed properties and respond to changes using watchers.

Handle user input with two-way data binding and form events. Process and validate form data in a structured way.

Apply styles to components using CSS and scoped styles. Control appearance dynamically using class and style bindings.

Build a complete Vue application from scratch by combining components, state, and interactivity. Structure the UI, manage data, and refine the final result into a working app.
