🚀 Node.js Fundamentals You Should Actually Understand Node.js isn’t just about writing JavaScript on the server. This new CodeMane carousel breaks down 3 important concepts: 🔹 Streams — Process data in chunks instead of loading everything into memory. 🔹 Modules — Structure your application using reusable pieces of code. 🔹 CommonJS vs ESM — Understand require() vs import and module.exports vs export. 💡 These concepts become especially important when you’re working with real-world Node.js applications. 📌 Save this one for your next Node.js project. 👉 Read the full carousel on Instagram: https://www.instagram.com/p/Db5-lWDE5OY/?igsh=MTRtYnY2eDBkNXQyOA== 💬 What Node.js concept should CodeMane explain next? — Follow CodeMane.dev for more useful contents.

🚀 Debouncing vs Throttling — What's the Difference? Ever wondered why some apps don't trigger an API call for every single user action? That's where Debouncing & Throttling come in 👇 🟢 Debounce → Wait until the activity stops → Then execute once Great for: • Search • Autocomplete • Form validation • Autosave 🔵 Throttle → Control how frequently something executes → Even while events keep happening Great for: • Scroll • Mouse movement • Dragging • Resize events 🧠 Easy way to remember: Debounce → "Stop, then I'll run." Throttle → "I'll run, but not too often." 💡 Fewer unnecessary operations = Better performance = Better UX 🎥 Watch the full Reel: https://www.instagram.com/reel/Db3XuOPzMOE/?igsh=YWwwbDF0ZWhkMDlz Follow @codemane.dev for more such useful contents.

🚀 New CodeMane Post! Not all state is created equal. 👀 A modal being open is state. A user's profile fetched from your backend is also data your UI needs. But they have VERY different problems. In this carousel, we break down: 🔹 Client State vs Server State 🔹 What "Stale State" actually means 🔹 Why Server State is different 🔹 Why TanStack Query (React Query) exists 🔹 How to think about caching & refetching The key question isn't just: "Where should I store this data?" It's: "Who owns it?" "How fresh is it?" "When should it be fetched again?" 🧠 Once you understand this mental model, React Query becomes much easier to understand. 👉 Read the full carousel on Instagram: https://www.instagram.com/p/Db3CPQpk5CU/ Follow @codemane.dev for more practical software engineering concepts.
