Feature Request: Conditional Logging options

[gabrielOttopia]

Description / Use Case for a Feature

I often times want only to log something if an action fails. It would make my code a lot cleaner if i could do something like
logger.conditional.info(true, "log msg")
or info.conditional

I could create a function that does this but it would be nice to be built into the logger!

Still open as a feature request. v5 doesn't add logger.conditional.info(cond, ...) sugar. The closest built-in is isLevelEnabled() (which gates expensive log construction), but that isn't the same as a per-call condition:

if (!ok) logger.info("action failed");
// or a tiny helper:
const logIf = (cond, fn) => { if (cond) fn(); };
logIf(!ok, () => logger.info("action failed"));

Leaving this open — a first-class conditional API is a reasonable enhancement to consider, separate from the v5 release.
