 ## React Native
 
-Status (formerly known as Syng) has always aspired to have a single, unified codebase for multi-platform development. This is not so easy to achieve, as many of the non-web-based solutions out there allow you to have a semi-single codebase, but you find yourself creating a lot of seperate logic for handling user interfaces on each platform - Status is 80% frontend code and this presents a problem. We tried Xamarin & Java (EthereumJ was the first implementation we got running on Android & iOS - via RoboVM), and we quickly discovered this problem.

-Mobile apps built on web-based technologies, such as those done in Cordova, are great for short-term projects or mvp, but you will quickly run into performance issues on resource-limited devices and may need to rewrite you app. In our tests displaying webview DApps in a chat history with iFrames and all the other bells and whistles we wanted turned out to be a futile effort.

 That limited our options to choosing between NativeScript & React Native. We chose React Native because it is more mature and is being used in production for popular apps like **Facebook**, **Instagram**, **Airbnb**, **Baidu** & **Discord**. This gave us the impression that this framework was here to stay with many Fortune 500 companies invested in its continuance.

-There's alot of resources online about why learning Lisps are so great. For us, it's largely about culture; we like the way Lispers think. We want functional programming, macros, homoiconic code and the flexibility that comes with a simple, unstructured language in which to think. The benefits of this become more apparent in later stage development, where functional language allows us to perform rewrites more easily, isolate many bugs to specific functions, as well as enforcing correct coding. Also, I prefer reading it.

+[Reagent](http://reagent-project.github.io/) provides a minimalistic interface between ClojureScript and React. It allows you to define efficient React components using nothing but plain ClojureScript functions and data that describe your UI using a Hiccup-like syntax.
 The goal of Reagent is to make it possible to define arbitrarily complex UIs using just a couple of basic concepts, and to be fast enough by default that you rarely have to care about performance.
