Logger with formatter.
This Logger accepts the argument and formats it before logging apart from logging at different levels.
npm install console_log
Placeholders may contain numbers which refer to positional arguments:
const msg1 = '{0}, you have {1} unread message{2}';
log.info('Holly', 2, 's');
// => 'Holly, you have 2 unread messages'
Unmatched placeholders produce no output:
'{0}, you have {1} unread message{2}';
log.warn('Steve', 1);
// => 'Steve, you have 1 unread message'
A format string may reference a positional argument multiple times:
"The name's {1}. {0} {1}."
log.debug('James', 'Bond');
// => "The name's Bond. James Bond."
