Be it a matter of simple or comprehensive app development, deciding the features to keep is not as difficult for the businesses as it’s tough to pick the right tools, frameworks, and methods from the technology stack. Sometimes, it even became a matter of Immaculate debate as the selection of platforms and technologies plays a vital role in meeting business goals.

Indeed, performance, quick time-to-market, stability, budget, and popularity are the factors that taken into consideration before deciding the best fit. Here, we will compare the two frameworks- React Native and Kotlin which are getting more up-to-date and adding flexibility to create something new.

Of course, both can’t be leveraged and have their own pros and cons. Also, each framework outweighs another in some areas. Let’s evaluate the advantages and disadvantages of the two to determine which one brings all good and glory to your project.

Here’s a quick comparison of the two developer’s fave frameworks- React Native and Kotlin:

1. Performance

React Native development offers excellent performance using native controls and native modules wherein the UI components are compiled to native modules, and JavaScript bridge is used to interact with native components and render the code to native APIs squarely. The use of separate threads from UI enhances the React Native app performance. However, it’s not an excellent fit for the computation-intensive apps as the performance gets immensely degraded and float computations are handled in inefficient ways.

Thanks to bytecode structure and support for inline functions, which allow the Kotlin app’s code using lambdas to run as fast as the equivalent JavaScript app one. The incremental compilation decreased compile-time, which increases the developer’s productivity.

2. Development time

React Native features hot reloading that makes app development time-efficient in the sense of enabling the developers to visualize how the design and layout created would look like. The live preview of the changes made in the code reduces the waiting time for viewing the changes in Android and iOS app variants to nil. Besides, the array of ready-to-apply components eliminates the need for writing the code from scratch thereby basic functionalities can be implemented in a couple of minutes, which makes the development process faster.

Kotlin has very clean, clear and concise code-base. It indicates the developers have to write less code to build the functionality, which is a sign of fewer mistakes. By doing so, the time required to test the errors and fix them will get minimized, and the app development time will decrease by a large fraction. However, the slow compilation time is the major drawback of Kotlin.

3. Perfect fit for budget-constrained projects

In addition to reduced development time, React Native also boasts of the less budget needed to build the native-like app for the various platforms. Embracing React Native framework, hiring JavaScript developers is alright who can develop the app targeting multiple OS with minimum native code. In this way, reduced resources and dollars to spend on building the same apps. In the event of comprehensive app development with advanced functionalities, extra resources, time, and money investment are essential.

Obviously, the reduced development time, fewer resources, and minimum errors lead to a lesser amount to spend on mobile app development solutions. The lower cost of development of Kotlin projects is the biggest plus for the businesses, but the programming language won’t enable cross-platform development. The companies won’t get the apps for diverse platforms at the price of one.

4. Community size

Both the platforms are open source that allows developers worldwide to contribute to the framework. Being an old and trustable framework, the React Native developers have a high probability of getting help and required assistance from the experienced developers, in case they face any issue. The community was growing and anticipated to become huge in the years to come.

The newbie Kotlin has successfully garnered enough attention in the Android development space, but still, its community is small. Even after having a huge sea of information, the lesser developers are learning the Kotlin language, and that’s why most of the queries regarding Kotlin development remain unsolved and unanswered.

5. Learning curve

Despite having ready-made component availability, less native code requirement, and maximum use of the JavaScript language, learning React Native and developing the app using the same framework is a little tough for an average Joe as compared to other cross-platform alternatives. The reason is JSX is used in React Native app development which is not plain-sailing to learn, which makes the learning curve steep.

The initial learning curve of Kotlin is pretty low, and the experienced Java developers can pick up and start developing the apps in a matter of hours. But, for the rookie players, training is a must to get up to speed. Plus, there is a ton of resources available to learn and master coding in Kotlin.

6. Stability

The giants including Facebook, Skype, Instagram, and Walmart are using the React Native framework which itself speaks about the stability and reliability it offers. Making the upgrade or changes to React Native is simplified with data binding where the child elements won’t affect parent data upon any, and the changes can be reflected in the specific components without modifying the states of other objects to apply updates. Not to say, but security is low because JavaScript is known for its fragility. That is why mobile app developers need to beware of malicious code snippets, especially when using third-party add-ons.

Kotlin is maintained by tech giant JetBrains and supports different development environments which ensure that developers will continuously get the tool support and can use Kotlin across multiple tools and IDEs. Additionally, it’s a mature language that’s updated the number of times after rigorous testing from the developer’s perspective. When you have to deal with Android’s device fragmentation problem, Kotlin is a great alternative to consider.
