What is the use of script in vue

The script tag in Vue defines the logic and behavior of the component, including data, methods, computed properties, listeners, and life cycle hooks. It also provides component templates and works with other Vue tags, parsed by the compiler and converted into executable JavaScript code.

The role of the script tag in Vue

The script tag plays a vital role in Vue.js , which is used to define the logic and behavior of the component. The following is the main role of the script tag in Vue:

Define component logic

The script tag contains the JavaScript code of the component, which defines the following aspects of the component:

• Data (data): Private and responsive data of the component, used to store and track the state of the component.
• Methods: Functions that handle user interaction or perform operations.
• Computed property (computed): A dynamically calculated value based on other data or methods.
• Listener (watch): Monitor changes in data attributes and perform corresponding operations.
• Life cycle hook: Function executed at different life cycle stages of the component, such as mounted, updated and destroyed.

Provide component template

Inside the script tag, you can use the template tag to define the HTML template of the component. The template provides the structure and content of the visual part of the component, using data and methods to dynamically render the data.

Works with other tags

The script tag works with other Vue core tags, for example:

• v-bind : Bind data to HTML attributes.
• v-on: Listen to HTML events and execute methods.
• v-if: Show or hide elements based on conditions.

Parsed by compiler

In Vue.js, the content of the script tag will be parsed by the Vue compiler and converted into JavaScript code. The compiler parses the component's logic and templates and compiles them into executable JavaScript functions.

Summary

The script tag in Vue defines the logic and behavior of the component, including data, methods, computed properties, listeners and life cycle hooks. It also provides a component template that is parsed and converted into executable JavaScript code by the Vue compiler.
