However, this can be a difficult task, especially if the codebase is already large before you start. This is why many developers choose to integrate Flow or TypeScript to help with this. That means that even legacy code written by previous teams doesn't have to be rewritten when updating to a new version of Kotlin.Ī big problem with large javascript projects is the errors that can come up due to the lack of typing. However, with writing Kotlin, each new version is backwards compatible with the last. Many of us have suffered through the pain of having to update React or React Native. Kotlin, on the other hand, appears and acts totally natively without lag. For advanced functionality or heavy computation, the overhead of using React Native can considerably slow down an app. Any API that supports Java 8 can be easily used with Kotlin.Īnother big reason to prefer native code over React Native is performance. Kotlin, on the other hand, is strongly supported within the Android ecosystem and is interoperable with Java so it has easier access to these APIs. This can be tricky to developers who may not have ever written native code. This leads to developers having to write native code to get the functionality they need. Many services that have APIs for apps cannot be used fully within React Native. One of the most common I have seen is API support. There are many reasons why one may choose to write native code for an app rather than React Native. I will talk through some examples of why Kotlin might be a better choice in some cases. But this doesn't mean that we should necessarily use React Native in every case. It has a rich ecosystem of libraries to use, hot reloading out of the box, is very similar to React which is a hugely popular web framework, and vitally it allows you to compile your apps to both Android and iOS from just one codebase. It was created by Jetbrains, the makers of hugely popular IDEs like IntelliJ and P圜harm, and is used by big companies such as Pinterest, Uber, and Atlassian.Īt Theodo, React Native is the language of choice for building apps. Kotlin is an object-oriented programming language for making Android apps that uses Java-like syntax with functional programming features.
