Error handling is a critical aspect of GoLang programming. In 2024, it's essential to understand how to handle errors effectively using GoLang's built-in error type and err wrapping. It visualizes goroutine creation

While pprof gives you an aggregate view of performance, the runtime execution tracer ( go tool trace ) offers a microscopic look at latency. It visualizes goroutine creation, network unblocking, system calls, and GC pauses on a timeline, helping you diagnose complex latency spikes. Conclusion
