What is the benefit of using console.log
vs console.info
?
Or any of the other console commands for that matter?
console.info("info"); console.error("error"); console.warn("warn");
vs
console.log("log");
I thought it might change the color of the output or concatenate some sort of label, but they seem to all do the same thing. And according to the documentation here:
https://nodejs.org/api/console.html#console_console_info_data
they seem to all do the same as console.log

According to the documentation that you linked to, console.error
and console.warn
outputs to stderr
. The others output to stdout
.
If you are doing piping or redirection from node.js
the difference is important.
There is a lot of JavaScript written to run in both the browser and Node.js
. Having node implement the full console allows for greater code cross-compatibility.
In most browsers, not only do these log in different colors, but you can also filter to see specific messages.
console.info("info"); console.error("error"); console.warn("warn"); console.log("log");
