Vue.js 3 and Firebase for Beginners - Options or Composition?

The video tutorial introduces Vue.js's Options and Composition APIs, explaining their roles in building applications. It details the traditional Options API, highlighting its components like data, methods, and lifecycle hooks. The Composition API is presented as a modern alternative, offering a more JavaScript-like coding style. The tutorial also covers Vue's reactivity system using ref and demonstrates the script setup for cleaner, more efficient code. The focus is on understanding these APIs' functionalities and how they can be used together for optimal performance.

What is the primary purpose of the Options API in Vue.js?

• To replace the Composition API

• To organize component data and methods in a structured way

• To provide a new way of writing JavaScript code

• To enhance the performance of Vue.js applications

How does the Composition API differ from the Options API?

• It allows writing code more like regular JavaScript

• It uses a different syntax for lifecycle hooks

• It is only available in Vue.js version 1

• It does not support reactivity

What is the role of the setup function in the Composition API?

• To manage component styles

• To organize and return variables and functions for the template

• To define the template structure

• To initialize the component's lifecycle

What is the purpose of using 'ref' in the Composition API?

• To manage component lifecycle

• To create non-reactive variables

• To make variables reactive

• To define component styles

What advantage does the script setup syntax offer?

• It is only compatible with Vue.js version 2

• It does not support reactivity

• It automatically makes data available to the template without a return statement

• It requires more code to achieve the same functionality
