what is the '\x1Bc' it look like a regular expression, why does it clear the console

@TheRealCasadaro It's an ANSI Escape Sequence which clears the screen and buffer for the terminal output. It basically becomes <ESC>c which is the VT100 escape code for resetting the terminal.

}

console.clear() does the trick without having to use keyboard shortcuts every time you run your js files

The below is better, because it clears also scroll-back buffer

process.stdout.write('\033c\033[3J');

ESC [ 3 J: erase whole display including scroll-back buffer (since Linux 3.0).

Node 5 strict mode requires this, which is the same as jimmywarting's answer but it also resets the cursor:

process.stdout.write('\x1B[2J\x1B[0f');

Thanks, its work on windows 10

The combinations Ctrl + L reset the full log.

Thank you.
If anyone is wondering when/how to call the function, the following is working for me :

app.listen(process.env.PORT || 3000,function (){
  process.stdout.write('\033c'); 
}

since app.listen accepts a callback method, hope this helps someone ! :)
