Go slog Structured Logging
Go 1.21 introduced the slog package as the standard structured logging solution. Master vocabulary for the key-value variadic API, typed attributes (slog.String/Int/etc.), the Handler interface and Record.Attrs iteration, child loggers via With(), Enabled() pre-checks, and JSONHandler for production use.
slog.Info("request", "method", r.Method, "path", r.URL.Path). How does slog interpret the alternating string/value arguments?slog.Info variadic args parameter accepts alternating key-value pairs: odd-indexed arguments are string keys, even-indexed are values. This is the 'loosely typed' API. For performance-critical code, prefer slog.String("method", r.Method) typed attributes to avoid interface boxing.Frequently Asked Questions
