Chrome/Firefox console.log always appends a line saying 'undefined'

Question

Every time console.log is executed, a line saying undefined is appended to the output log.

It happens in both Firefox and Chrome on Windows

Answer 1

What you can do is simply create your own console.log like function with a return to change this behavior when doing a lot of coding in the developer console. Here is an example of what that looks like in the developer console:

console.log('I hate seeing the next line stating the obvious.')
I hate seeing the next line stating the obvious.
undefined
log = function(l){return l}
function log()
if(1 === 2){console.log('1 is not equal to 2.')}else{log('No Shit Sherlock.')}
"No Shit Sherlock."
