By the end you&rsquo;ll know how to configure handlers, set log levels, attach structured attributes, carry loggers through <code>context.Context</code>, write your own handlers, and redact sensitive fields.</p> <p>We&rsquo;ll also make the case for <em>why</em> <code>slog</code> has become the default choice for new Go projects, and why it makes third-party loggers like <code>logrus</code>, <code>zap</code> and <code>zerolog</code> hard to justify reaching for anymore.</p>
