Hi, I want to contribute. New to open source, Pretty good in js, How can I begin? @GantMan

This one has a React example and we need a React Native version. Take a look at other state libraries that have both a working react and react native example and do that for react-copy-write. If you do so in a fork, you can then send a pull-request to be a contributor.
