include filename and line number with log message

[dylang]

I think it is important to note that when console.* is called, browsers* should show the line number and filename in the console mapped to filename and line where the call was made. When a source map is available, the original line number and file names should be displayed instead.

Moreover, I would like to propose introducing a method to enable the correct line number and filename to be displayed when calling console functions through a console abstraction library**.

For example: Angular provides a console.log abstraction called $log. Using $log results in every call displayed as if it originated in angular.min.js on line 79. This solution would enable the log messages to include the line number and filename of where $log.* was called instead.

• Node does not currently show this information but it should make it available.
