For @johnguerra.bsky.social's @northeasternu.bsky.social #ProgramDesignParadigms class I built an @observablehq reactive widget that lets users upload labeled photos and preview them! 📸 Great for family trees or user profiles.

Using transformer.js is like having a full AI library in your pocket. You don’t need to call a server — it's all in your browser, like carrying a mini AI lab wherever you go!

Observable notebooks feel like magic—just built a live weather dashboard that pulls real-time data and updates visuals instantly. No page reloads, no deploys, just tweak and see. Feels like prototyping at the speed of thought.

Test-Driven Development (TDD) is like building a safety net for your code!
✅ Banking apps: Prevents transaction errors.
✅ E-commerce: Ensures smooth checkout.
✅ Self-driving cars: Validates decision logic.
Catch bugs before they bite!

Used crypto exchanges with real-time charts & instant trades? Parallel programming powers order matching engines executing thousands of trades in microseconds. Web Workers process live updates without freezing the UI. Fast data, smooth experience.

Ever wondered how code editors lint in real-time or maps update live without lag?

Web Workers process heavy tasks off the main thread, keeping web apps smooth. From data processing to AI-powered suggestions, they do the heavy lifting.

JavaScript's Event Loop: The unsung hero of async magic!

It constantly checks:
✅ Is the Call Stack empty?
✅ Any callbacks waiting in the Queue?

If yes, it moves tasks to execution—keeping JS non-blocking & smooth!

Asynchronous programming is like texting a friend while baking a cake. You don’t wait for the oven to finish—you prep the frosting, clean up, or check your phone. Your program, like you, keeps doing useful work while waiting!

Immutable data in functional programming is like a whiteboard that you can write on, but never erase or overwrite—only add new notes 📝. This keeps everything predictable and avoids unexpected changes! #ProgrammingParadigms @northeasternu.bsky.social

Think of JSDoc like a roadmap for your code. Just as a map helps travellers navigate, JSDoc comments guide developers through the complexity of the codebase. #ProgrammingParadigms @northeasternu.bsky.social

Designing flexible software? 🤔 Use interface polymorphism!

Instead of tying your code to a single implementation, use an interface to easily swap in new versions.

💡 Program by interface, not implementation!

PerspectiveCamera in threejs is like looking through a window. The field of view adjusts how much you can see, the aspect ratio keeps things proportionate, and the near/far clipping planes act like your focus range—everything outside is out of sight. #ProgrammingParadigms @northeasternu.bsky.social

Parents (superclasses) pass down traits (properties & methods) to their children (subclasses), but kids can still develop their own unique quirks (overrides). #ProgrammingParadigms @northeastern.bsky.social
