This JavaScript library is a response to this coding task: https://steemit.com/utopian-io/@utopian.tasks/js-developers-and-regex-experts-wanted-javascript-coding-task
I've used node.js and ES6. This code should work in recent browsers sans the testing part, which I'm not sure will work (I haven't used jest [the testing suite] on the client-side yet.)
I'm using regular expressions for most of the parsing. Exact expressions with the explanation are available here: https://github.com/Ominousness/utopian-beneficiaries/blob/master/beneficiaries.js#L7
Most of the sanity checks happen in the Javascript part, though.
Unit tests are also included to check for regressions that may happen on accident.

The project will serve its purpose once it's used in the bot code.
