Firebase Quiz For Beginners

The Firebase SDK for JavaScript is a library provided by Firebase for integrating Firebase with a JavaScript application codebase. It provides a set of APIs for accessing Firebase services, such as the Realtime Database and Authentication, from a web application.

To initialize Firebase in a JavaScript application, you need to call the firebase.initializeApp() function with the Firebase configuration object as a parameter.

Firebase Cloud Functions is a serverless computing service that allows developers to run backend code in response to events triggered by Firebase or third-party services. Developers can write their functions using JavaScript, TypeScript, or Node.js.

Firebase is a Google platform that provides various services such as hosting, databases, storage, and authentication for developing web and mobile applications.

A container for all Firebase resources and services. A Firebase Project is a container for all Firebase resources and services, including authentication, databases, storage, and hosting. It can have multiple Firebase Apps associated with it.

Firebase offers two database options: Cloud Firestore and Realtime Database. Cloud Firestore is a NoSQL document database that can store, sync, and query data for your mobile and web apps at global scale. Realtime Database is a cloud-hosted NoSQL database that stores data as JSON and allows for real-time data synchronization.

Firebase offers two database options:

1. Cloud Firestore: a NoSQL document database that can store, sync, and query data for your mobile and web apps at global scale. It is designed to handle large amounts of complex data and is suitable for real-time data synchronization.
2. Realtime Database: a cloud-hosted NoSQL database that stores data as JSON and allows for real-time data synchronization. It is suitable for small to medium-sized apps that require real-time updates and low-latency access to data.

Both databases have their own unique features and benefits, and the choice between the two will depend on the specific needs of your application.

A Firebase App cannot be associated with multiple projects. Each Firebase App is associated with only one Firebase Project. However, a Firebase Project can have multiple Firebase Apps associated with it. This means that you can create multiple Firebase Apps for the same project, but each Firebase App will have a unique App ID and can have its own configuration settings.

Firebase Analytics provides various features for analyzing user behavior, including user engagement tracking, crash reporting, and event tracking. However, it does not provide ad targeting features.

Cloud Firestore is a database developed by Firebase specifically for mobile app development. It is one of the newest additions to the Firebase platform and provides a scalable and flexible solution for storing and syncing data in real-time across multiple devices and platforms. Realtime Database is Firebase's original database.

To implement real-time updates in a JavaScript application using Firebase Realtime Database, you can attach listeners to database references in the JavaScript code using functions such as on(), once(), and off(). This allows the application to receive real-time updates whenever data changes in the database.

A service that helps you manage users in your application. Firebase Authentication is a service that allows you to authenticate users using various providers such as Google, Facebook, and Twitter. It also allows you to manage user authentication and authorization.

Firebase Cloud Messaging is a service that enables developers to send push notifications to users of their mobile and web applications.

There are multiple ways to add the Firebase SDK to a JavaScript application, including adding the Firebase SDK script to the HTML file, installing the Firebase SDK using npm, and downloading and including the Firebase SDK in the project directory.

To deploy a JavaScript application using Firebase Hosting, you can use the Firebase CLI (Command Line Interface) to upload the application files to Firebase Hosting. This allows you to deploy the application with a single command and manage the deployment process more easily.
