About
The level of a log message dictates it severity.
Example
Standard
syslog (RFC5424) specifies that the order of severity is assumed to be numerically ascending from most important to least important.
Example: logging levels are prioritized from 0 to 6 (highest to lowest):
const levels = {
error: 0,
warn: 1,
info: 2,
http: 3,
verbose: 4,
debug: 5,
silly: 6
};
