Ever dealt with race conditions in Go? Here's a simple fix with sync.Once 🚀

Hi Friends! 🦫

Have you ever had that "Oops, did I just create two cache pools?" moment when working with Goroutines? Race conditions can be a real pain when multiple threads try to initialize the same resource.

Good news, though: Go's sync.Once makes one-time initialization super easy and safe. There are no complex patterns, just a simple built-in way to avoid those "Oops" bugs.

I wrote a quick guide explaining:
✅ Why Singleton Pattern matters in concurrent code
✅ How sync.Once keeps your code clean and safe
✅ Real-world code examples you can try out!

Would love to hear your thoughts—ever used sync.Once in production? How do you handle single-instance setups? Drop your feedback! 🚀
