    • options <Object>

        

      • stdout <stream.Writable>
        • 

      • stderr <stream.Writable>
        • 

      • ignoreErrors <boolean> Ignore errors when writing to the underlying
streams. Default: true.
        • 

      • colorMode <boolean> | <string> Set color support for this Console instance.
Setting to true enables coloring while inspecting values. Setting to
false disables coloring while inspecting values. Setting to
'auto' makes color support depend on the value of the isTTY property
and the value returned by getColorDepth() on the respective stream. This
option can not be used, if inspectOptions.colors is set as well.
Default: 'auto'.
        • 

      • inspectOptions <Object> Specifies options that are passed along to
util.inspect().
        • 

      • groupIndentation <number> Set group indentation.
Default: 2.

    Creates a new Console with one or two writable stream instances. stdout is a
writable stream to print log or info output. stderr is used for warning or
error output. If stderr is not provided, stdout is used for stderr.
    const output = fs.createWriteStream('./stdout.log');
const errorOutput = fs.createWriteStream('./stderr.log');
// Custom simple logger
const logger = new Console({ stdout: output, stderr: errorOutput });
// use it like console
const count = 5;
logger.log('count: %d', count);
// In stdout.log: count 5
    The global console is a special Console whose output is sent to
process.stdout and process.stderr. It is equivalent to calling:
    new Console({ stdout: process.stdout, stderr: process.stderr });
