Argparse error using NodeJS

[user987115]

Hello everybody,

I am doing a Node JS project and need to use the argparse module to parse arguments. I call for the parser like this :

var parser = new ArgumentParser()
parser.add_argument(<argument>)
var args = parser.parse_known_args()
console.log(args)

Problem is, when my parser encounter an unknown argument it exits the function and shows me the help message. I would like to know how to fix it. I have read that this was a common error in Python which was fixed using :

args, uknownargs = parser.parse_known_args()

But how can I fix it in node JS ?

Thank you for your help !
