Top Pros & Cons Comparison: React Native VS. Kotlin

Pros of React Native: —

Time Efficiency

Design and layout feels a lot more productive if you are quickly able to visualize what you create. For that very purpose, React Native has a great feature called “hot reloading”. It allows the changes made in the code to immediately take effect into iOS and Android app variants. It’s like a live preview!

This reduces the waiting time for changes to show up to zero and saves further development time as well.


By using native controls and native modules, React Native improves on performance.

React Native interacts with the targeted (native) components for iOS or Android and renders code to native APIs directly and independently. In doing so, it uses a separate thread from UI, which results in increases the performance. The key factor here is React using the native APIs. Other options like using a WebView to render code may have other advantages, but compromise the performance.

Growing Community

As I mentioned above, React Native is an open source project. That means anyone can contribute to the framework. It also means you get to have a more approachable access to great developers and their experience. If you are facing any issues, you have high chances of getting the right kind of help from the community and experts.

Ready-made Components Increase Development Speed

Another great feature on the React Native table is the ‘Ready-to-apply components’. Instead of writing code from scratch, you get to use ready-made components. They are great for achieving simple forms of functionalities. It not only makes the development process simple but also faster.

Save Money

React Native can save big on money as well as time.
Aside from reducing the app development process (which is another way React reduces on cost), React Native enables JavaScript developers to create apps targeting multiple OS, with only a minimal amount of native code necessary.

This approach is cheaper and more budget-friendly because you don’t need to hire separate developers or teams for different development targets. One developer codes for two platforms — That is less amount of resources and costs spent on building the same apps with smaller development cycles.

Short Team Size

Building up on my last point, when one developer codes for both iOS and Android, it evidently reduces the team size as well. Apart from this being a great advantage for not needing to learn two different languages and platforms, it adds in great with a smaller team size too.

Having a single team vs having two different teams, an Android team and an iOS team, beats the later with potential better communication. By choosing React Native, you would, at the very max, need a great JavaScript developer who can write code for both (Android and iOS) platforms.

Yes, there might be times when apps with more native features will require help from native developers but in most cases, you will have a smaller team and it will be easier to manage.

Reliable and Stable Apps

You needn’t worry about the stability and reliability of Apps built with React Native. It simplifies data binding with such flow that the child elements cannot affect the parent data. If the developer wants to change any object, he/she would have to modify its state and apply updates accordingly — meaning only allowed components will be upgraded. Great companies like Facebook, Instagram, Airbnb, Skype and a lot more are using React Native for their apps! That, in itself, says quite a lot about the quality, stability and reliability of apps created using React Native.

Ability to Target Multiple OS with Less Native Code

The ability to create one app running for multiple OS is just great. No matter the simplicity because you might not get all the features or advanced functionality in apt packages for apps created with React Native, but nonetheless, you will have two applications with the time, effort and resources for creating one.
I would always add this to my list of Pros of React native.

Better than Hybrid Native Experience

React Native offers a truly native user experience, unlike other hybrid tools that merely provide a native-style wrapper for browser-based apps. Since React native leverages the native components, the final products look and feel very real — as if created with the same native technology. If you are unaware of the technology used to build an app, you will not be able to differentiate between a simple app built with React native or an Android programming language or iOS.
