In 2017, we have seen an increased interest in the question of code sharing across React and React Native, mostly after Nicolas Gallagher took to the stage at React Rally to talk about react-native-web, a solution he has been using to build a web version of Twitter.

Since then, both libraries have been actively maintained, albeit by a limited number of contributors.

What is WebAssembly “WebAssembly is a new type of code that can be run in modern web browsers — it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages such as C/C++ with a compilation target so that they can run on the web. It is also designed to run alongside JavaScript, allowing both to work together.” - Mozilla Developers Network.
