Summary  
This chapter introduces component-based architecture, showing how to break an interface into reusable, self-contained units that include their own template, logic, and styling.

General domain of usage  
User interface development


As applications grow, managing everything in a single file becomes difficult. Vue solves this by using components.

A component is a reusable piece of the interface that contains its own structure, logic, and styling.

For example, instead of building the entire page in one place, you can split it into smaller parts like a header, a button, or a card.

```vue id="c3m9kq"
<template>
  <h1>Hello Vue</h1>
</template>
```

Each component focuses on a specific part of the UI. This makes your code easier to read, reuse, and maintain.

Vue applications are built by combining multiple components together to form the final interface.


Which of the following is the main benefit of using components in Vue?
