I am looking to work on the project for updating the p5,js library to ES6 for GSoC 2019. I have gone through the project description and the associated issues on GitHub. It seems to be an important part of the road map for 1.0 release and thus think this is a good and high priority project that I could work on.
It would be great if someone could guide me as to how I can start contributing to this project, to get a better understanding of the code base. I could help solve some solve issues or start planning according to these steps: https://github.com/processing/p5.js/blob/master/developer_docs/roadmap.md#es6-migration.
Also I would appreciate if I could get in touch with a mentor to further delineate the project details, so that I can draft my proposal accordingly.
