Many client-side libraries already support a JavaScript console object. Since this functionality is useful on the server, and to ease migration of client-side JavaScript to the server, server-side JavaScript platforms need to provide a "console" object suitable for use with minimal modification to existing scripts. Rather than provide a "console" free variable like web browsers, interoperable JavaScript modules may explicitly import the "console" module and bind it to a module local "console" variable.

Specification

The "console" top-level module must be available in all platforms. The module must provide the following exports:

log(message) 

logs a message

info(message) 

logs an informational message

warn(message) 

logs a warning message

error(message) 

logs an error message

Messages may be any reference. Names must be strings.
