React Native Development (Part 2): Improving Performance

In the last article in our React Native series, with the help of the architecture diagram we saw that React Native bridges the gap between JavaScript and Native components. The performance of piece of JavaScript code is equivalent if not better than ideal native code. However, that is not the case with the bridge though. The JavaScript realm cannot access data from the Native realm just like that because it's a completely different heap; it's a completely different address space. Data between the realms is serialized. This serialization is expensive and takes place every time you send stuff between realms inside your app.
