Your articles are always fascinating. I genuinely prefer learning through engaging narratives like yours rather than through dry tutorials — so thank you for that, Aaron.
Just a simple question, more out of curiosity than anything else: have you ever considered grouping your Go, JavaScript, and other pieces into structured series instead of keeping them standalone? I feel like they already form a kind of narrative universe, and seeing them organized as series could make them even more powerful for readers following along.
i'll check that out! thank you Pascal 🙏❤
This is a great explanation of
defer👍I really like the proximity rule framing — opening a resource and immediately deferring its cleanup makes the code much safer and easier to reason about. The LIFO example and the argument-evaluation gotcha are especially helpful for people who think they already “know” defer but still get bitten by it.

“Absolutely loved this deep dive into Go’s defer statement! Who knew that a tiny little keyword could have such a big impact on keeping your code clean and bug-free? The article really demystified the subtle behaviors of defer—especially the order of execution—which I’ve sometimes underestimated in my own projects. The examples were super practical and made me appreciate how defer can save us from common mistakes like forgetting to close files or unlock mutexes. After reading this, I’m definitely going to be more mindful about where and how I use defer. A must-read for anyone who wants to write Go code that’s both elegant and robust!”

Great read! 🙌 I love how this article breaks down Go’s defer in a clear and practical way — it’s one of those features that seems simple but can be surprisingly powerful (and tricky) in real code. Thanks for the helpful insights!
🙏❤✨
nice! Go looks much easier than javascript?
Hi Benjamin, yep Go is definitely simpler by design, which makes it feel much less cluttered! While JavaScript is still the king of the browser, Go shines on the backend where you need raw speed and reliability. Cheers! ✨❤
Nice! I need to take some time to learn GO. I don't use node.js for the backend anymore.
That was a great way of explaining defer in Go, learnt new things for sure, thanks mate!!
🙏❤️🌹
