🎯 Ever tried preventing multiple instances of an object in Go?

If you've battled race conditions with multiple Goroutines trying to initialize the same resourceβ€”whether it's a cache pool or a loggerβ€”you know the struggle is real!

Good news: Go's sync.Once makes it ridiculously simple to ensure safe, one-time initialization. No more worrying about complex thread-safe code! πŸš€

πŸ“– In my latest article, I break down:
βœ… Why the Singleton Pattern matters for concurrent applications
βœ… How sync.Once helps prevent race conditions with minimal code
βœ… Real-world examples + code you can try right away!

πŸ“Œ Code examples in my GitHub repo: https://github.com/architagr/The-Weekly-Golang-Journal/tree/main/sync_once

Let me know your thoughtsβ€”Have you used sync.Once in your projects?
