8 Subtle Go Language Details You Might Not Know

This article walks through eight often‑overlooked Go features—including direct integer iteration in Go 1.22, the ~T generic constraint, UTF‑8 string length pitfalls, nil‑interface quirks, nil‑pointer method calls, proper timer usage with contexts, zero‑size struct semaphores, and the JSON "-" tag—showing concrete code examples and the reasoning behind each behavior.

Understanding and Using Empty Structs (struct{}) in Go

This article explains the zero‑size nature of Go's empty struct, demonstrates how its memory address behaves, shows its impact on struct alignment, and presents multiple practical patterns such as set implementation, large arrays, signal channels, no‑op methods, interface stubs, and the noCopy identifier.
