Need to split and assign variables given on the command line?

Question

JavaScript

Query example: I found out that process.argv stores all options given on the command line. But I can't figure out how to take values ​​from process.argv and assign them to DIR and PATTERN. Also, according to the task, the order of the parameters can be different.
node index.js --DIR="/Downloads" --PATTERN=\.js

Answer 1

https://www.npmjs.com/package/minimist or https://www.npmjs.com/package/yargs
What's the problem anyway? We go around the process.argv array starting from the second element, and see what lies there.
