1. **Difference between React and other front-end frameworks**:
   - React is a library for building user interfaces, while other frameworks like Angular and Vue.js are full-featured frameworks.
   - React follows a component-based architecture, promoting reusability and modularity.
   - React uses a virtual DOM for efficient updates to the UI.
   - React primarily focuses on the view layer of the application.

2. **JWT (JSON Web Token) and how it works**:
   - JWT is a compact, URL-safe means of representing claims to be transferred between two parties.
   - It's commonly used for authentication and information exchange in web services.
   - JWTs consist of three parts: Header, Payload, and Signature.
   - The token is generated on the server, signed with a secret key, and sent to the client.
   - The client includes the token in subsequent requests, and the server verifies its authenticity before granting access.

3. **Why we use bcrypt**:
   - Bcrypt is a password-hashing function designed to securely store passwords.
   - It incorporates a salt to protect against rainbow table attacks and uses a computationally intensive hashing algorithm, making brute-force attacks impractical.
   - Bcrypt helps enhance the security of user authentication systems.

4. **How you debug the code**:
   - Use browser developer tools for client-side debugging.
   - Print statements and console.log() for logging and debugging.
   - Utilize debugging tools provided by IDEs or text editors.
   - Use breakpoints to pause code execution and inspect variables and states.

5. **How you will start a project**:
   - Define project requirements and objectives.
   - Set up version control and project structure.
   - Choose the appropriate stack and development tools.
   - Design database schema and system architecture.
   - Implement core features iteratively, starting with MVP.

7. **MVC (Model-View-Controller)**:
   - MVC is a software design pattern used for developing web applications.
   - Model represents data and business logic.
   - View displays the user interface and interacts with the user.
   - Controller handles user input, processes requests, and updates the model and view accordingly.

6. **Steps to start a YouTube-like project from scratch**:
   - Define user stories and feature requirements.
   - Design database schema for users, videos, comments, etc.
   - Set up user authentication and authorization.
   - Implement video uploading, storage, and streaming.
   - Develop features like likes, comments, subscriptions, and recommendations.
   - Ensure scalability, security, and performance.
Sure, here are the steps to start building the frontend for a YouTube-like application from scratch:

1. **Define Requirements**:
   - Gather requirements for the application, including user stories, features, and functionalities.

2. **Plan User Experience (UX)**:
   - Design the user interface (UI) considering usability, accessibility, and responsiveness.
   - Plan the layout, navigation, and visual design elements.

3. **Set Up Development Environment**:
   - Choose appropriate tools and technologies for frontend development, such as React.js, HTML, CSS, and JavaScript.
   - Set up a code editor, version control system (e.g., Git), and development server.

4. **Create Wireframes and Mockups**:
   - Develop wireframes and mockups to visualize the UI components, layouts, and interactions.
   - Use tools like Figma, Sketch, or Adobe XD for designing.

5. **Implement Basic Structure**:
   - Set up the project structure with folders for components, styles, and assets.
   - Create the main layout components, such as header, footer, and sidebar.

6. **Build Core Features**:
   - Develop components for video playback, video lists, user authentication, and navigation.
   - Implement features like video search, user profiles, subscriptions, likes, and comments.

7. **Integrate APIs**:
   - Connect the frontend to backend APIs for fetching and updating data, such as video metadata, user information, and authentication tokens.

8. **Optimize Performance**:
   - Optimize assets, images, and code for fast loading times and smooth user experience.
   - Implement lazy loading and code splitting to reduce initial bundle size.

9. **Test and Debug**:
   - Test the application thoroughly for functionality, compatibility, and responsiveness across different devices and browsers.
   - Debug issues and fix errors using browser developer tools and testing frameworks.

10. **Deploy and Monitor**:
    - Deploy the frontend application to a hosting platform or server.
    - Monitor performance, user feedback, and analytics to identify areas for improvement and future enhancements.
