Prevent useEffect infinite loops and memory leaks

In this video, I explain when closures happen in JavaScript and how they allow functions to remember and access variables even after execution.

JavaScript async patterns 🔸 Callbacks → Simple, but can lead to “callback hell” 🔸 Promises → Chainable, better error handling → Great for parallel tasks (Promise.all) 🔸 async/await → Clean, readable, modern standard → Best for complex logic https://lnkd.in/gYrj4ixK #javascript #webdevelopment #frontend #backend #programming #softwareengineering

Most JavaScript problems aren’t about complexity. They’re about fundamentals. Common mistakes I still see: Using == instead of === Not understanding scope Poor async handling Callback hell Fixing these will improve your code quality instantly.

Why does the loading spinner sometimes never stop? No errors. No crash. Just spinning. It looks like a UI issue. But most of the time, it’s not. It’s an error handling problem. I wrote a simple breakdown of why this happens and how to fix it. Read here: https://lnkd.in/gPvF_iK7 #JavaScript #Frontend #Programming #WebDevelopment #SoftwareEngineering

🧠 JavaScript Closures (without overcomplicating it) Most developers use them… few actually understand them. A closure is when a function “remembers” the variables from where it was created, even after that scope is gone. Simple idea: You create a function inside another one The inner function still has access to the outer variables Even after the outer function has finished executing 👉 Sounds simple, but this unlocks powerful patterns. Now here’s the real insight: If you use React, you rely on this EVERY SINGLE DAY. Hooks like useState and useEffect are built on top of closures. That’s how React “remembers” state between renders Without using classes So in practice: 👉 Understanding closures = understanding React at a deeper level #javascript #reactjs #frontend #webdevelopment #programming
