I was looking for a RRule Generator Component in ReactJS because I (a back-end dev) am lazy af to build front-end component. It drains my energy and I stumbled upon "react-rrule-generator". And holy moly. It is no longer maintained, but it has a very beautiful code. Then I thought, I should search more open source projects where code is clean so I can learn more.

So, do any of you know any open source project, library code or whatever that you think has a very clean code?
