I did a Show HN about three months ago (https://news.ycombinator.com/item?id=12879179) and was so grateful for all the great constructive feedback I received, it really encouraged me to keep evolving the project. And I really have come very far since then.
So I thought I would share what I have achieved so far:
1. The original release was iOS only, but so many people told me I should build an Android version, so I did. Now both iOS and Android are completely open source on Github and they both use the same JSON grammar. Here's a recent post where I talk about how I designed the JSON-to-Native mappings on both iOS and Android: https://medium.freecodecamp.com/how-to-build-cross-platform-...
2. I've implemented functional programming in JSON. Yes, a function in JSON. I had to come up with a JSON grammar that can represent all aspects of a function like invocation, arguments, callbacks, call stack, recursive calls, subroutines, etc. If you're interested, check out the post I wrote about this: http://blog.jasonette.com/2017/02/15/functional-programming-...
3. I've implemented a "require" for JSON, so it can be used to parallel process multiple JSON objects from different sources, which I think is great for people who want to build a mobile app for their decentralized apps. I personally think decentralized apps will take off in 2017 and going forward for many different reasons, so this means a lot to me: I wrote about this here: http://blog.jasonette.com/2017/02/17/require/
These are just some I have worked on personally, but the REAL cool part is that the community has really picked up and many people have been contributing to the project. And I think THAT's the main reason why it's awesome. The fact that some nobody with no track record can just release something that resonates with enough people and anyone from around the world can just jump in and help. This is my first ever experience with an open source project and everything feels so magical to me. I hope to update you guys with even better news in the future!
