Minimum Working Example

const winston = require('winston');
const { format, transports } = winston;

const log = winston.createLogger({

Why do we have winston/logger.js#L63 and winston/logger.js#L271-L273, if when I run iRoachie's 'Minimum Working Example' above, it takes me to logform/errors.js#L15? How can I exercise winston/logger.js#L63 and winston/logger.js#L271-L273?
