console.debug()

The console.debug() method outputs a message to the web console at the "debug" log level. The message is only displayed to the user if the console is configured to display debug output. In most cases, the log level is configured within the console UI. This log level might correspond to the `Debug` or `Verbose` log level.

Note: This feature is available in Web Workers

Syntax

console.debug(msg [, subst1, ..., substN]);

subst1 ... substN
JavaScript objects with which to replace substitution strings within msg. This gives you additional control over the format of the output. See Using string substitutions in console for a description of how substitutions work.
