Memory leaks in Node.js aren’t always obvious — they creep in through event listeners, large closures, or detached structures that never let go of memory.

Using --inspect with Chrome DevTools transforms debugging into visibility. Heap snapshots help you visualise what’s holding your memory hostage, while timeline allocation tracking reveals when leaks start growing.

If you’re running complex server-side logic (especially with frameworks that mimic DOM behaviour), always inspect detached objects — they’re the hidden culprits that bloat your heap.

Mastering memory profiling isn’t just about fixing leaks; it’s about building efficient, stable, and scalable Node.js systems that thrive under load.
