Module/library to work with command line arguments?

Question

Command line

It is quite easy to work with command line arguments, but the code "spoils" from such ugly constructions:

let input = process.argv.indexOf('-i');
if(input < 0) throw error;
input = prcess.argv[input + 1];

Although it is quite working, it is not optimized and ugly. And I don’t feel like sawing my crutches, when this has probably already been done.
The question is simple. What modules/libraries are there in general and which ones do you use or recommend :)
PS I'm also interested in libraries for C++, that's why it got into the tags.
PPS And how to force bash to do addition on tabs of the combinations?
