A: Reflection gives your program “X-ray” vision into its own structure at runtime—letting you inspect or manipulate methods, fields, constructors, and even invoke those dynamically by name.

A: Absolutely. Open both a normal and an incognito browser window, join the chat under different names, and you’ll see messages update in real time—perfect for testing server-side logic and event handling.

A: Yes—the tutorial walks through creating a client folder with index.html, styles.css, and app.js. The UI updates in real time using DOM manipulation, reflecting “user joined”, messages, and disconnections.

A: When a user connects, their name and unique socket ID are stored. The server emits a user-joined event to others. On disconnect, it broadcasts a left event and removes the user from the active list. Real-time presence updates all around!

A: Nope—you just need Node.js, Socket.IO, a text editor like VS Code, and optionally the Live Server extension. The tutorial walks you through project setup, package installation, and crafting a socket server from scratch.

A: Socket.IO provides a higher-level, event-driven interface that uses WebSockets when available—but gracefully falls back to long polling in unsupported environments. This ensures robust, real-time communication even across varying client contexts.

A: No. Airbyte simplifies it by auto-creating the necessary schemas and staging tables in Snowflake during the sync process.

A: Definitely. Examples include: Healthcare: Aggregating patient records and test results from multiple systems Marketing: Integrating data from social media, ad campaigns, and web analytics into Snowflake for performance insights It’s a versatile data integration setup.

A: Absolutely. During pipeline creation, you can configure the replication frequency (e.g., every 24 hours)—Airbyte will handle periodic syncing accordingly.

A: Yes! When you sync data, Airbyte will auto-create the staging table and final table (e.g., titanic_test) in Snowflake—no manual setup needed.
