In 2025, clear code wins — but verbosity kills flow.
✅ Short, context-clear names keep logic front and center.
✅ Compact loops scan faster (both in CPU and human heads).
✅ Use longer names only when scope demands it.
When brevity wins:
- Local accumulators (s, v, i)
- Common Go handlers (w, r)
- Small, tight math functions
When to go long:
- Exported identifiers
- Variables living across dozens of lines
- Complex structs shared across packages
💡 I break down practical examples (slices, handlers, readers), show do’s and don’ts, and share quick checkpoints to keep your future self sane.
