The code is

console.log(process.argv[2]);

I get the following in console

node task.js ABC
'ABC'
<empty line>

Or without parameters (code is commented)

node task.js
<empty line>

How can i remove it?

EDIT: changed console.out to console.log

  • What is `console.out`? You are more than likely seeing that line because the function `console.out` returns *undefined* and the console will always output the return of whatever you typed in. – mwilson Mar 05 '20 at 16:26
  • Whoops, i meant `console.log` – Nodedoesntwork Mar 05 '20 at 16:29

You may try this: process.stdout.write("test") It will display your output directly to stdout, so It will not return empty line.

How do you edit existing text (and move the cursor around) in the terminal?

Or if you need 1 line up

process.stdout.write('\033[1A');
