Kotlin or React Native

Developing an app for your business on a single operating system is like opening just one window to see through your customers. Even so, spreading your business through numerous customers can give you humongous growth, but is a single operating system enough to reach the target users?

Looking at the present competitive scenario, mobile applications have proven to play a vital role in wide spreading businesses. Still, launching the app out of place will never be enough to establish a user base. It depends on the choice of mobile app development and your target audience.

This is why Cross-platform apps are an all-in-one solution for mobile users. It can be developed by minimizing the costs of hiring Android or iOS developers. To develop cross-platform applications, there are two main open-source platforms to choose from Kotlin or React Native.

However, making a wise decision on choosing the right platform is perplexing since both have pros and cons like other programs, don’t they?

Keeping that in mind, we are explaining here the basics, advantages, disadvantages, and use cases for you to choose an optimum cross-application development platform, whether it should be Kotlin or React Native.

What is Kotlin?

Kotlin is an open-source framework majorly used for Android app development. It utilizes JavaScript programming language to set up Integrated Development Environment (IDE), making it a preferable platform for Android app development.

As Kotlin uses Java language, codes become applicable to integrate into Kotlin projects by various Kotlin app development services without any hindrances. But, for developing an app project through Kotlin, enterprises need to hire Kotlin developers who can deliver enhanced functions and user interface in the application.

What is React Native?

Like Kotlin, React Native is also an open-source platform, but it is a Java framework introduced by Facebook. It combines both JavaScript and React (JavaScript library) that is widely used for developing native-app-like functions on individual iOS and Android.

There are various features of React Native, but the most advantageous factor by far is its reusability. The code templates of React are like ‘write once, use anywhere’, which means its codes can be implemented into any app development project. Because of this given benefit, there are several use cases of react native which will be showcased as you scroll further.

Kotlin vs React Native Pros Cons – Which is Better?

Like other app development platforms, even Kotlin and React Native have their advantages and disadvantages. So what do you choose between best for app development and how much knowing various about Kotlin or React Native?

For this reason, we are briefing here the specific pros and cons of Kotlin and React Native.

What are the Pros of Kotlin Platform

  • Interoperability: Kotlin is interoperable with Java as it utilizes byte code files that are operated on Java Virtual Machine.
  • Effortless Integration: As Kotlin is an SDK (Software Development Kit) of Java, it allows code and modules to be shared mutually with the developers. Moreover, the codebase parts can also be migrated to other files as well.
  • Quick Learning: Kotlin’s syntax is similar to other programming languages like Swift. Also, its syntax is concise enough to reduce the barrier in app development.
  • Native UI/UX: Unlike React Native, Kotlin contains guidelines and API components for Kotlin developers to flexibly create and modify the UI/UX design.

What are the Cons of Kotlin Platform

  • Beta version: Kotlin was introduced in 2018, which hasn’t been that long for its SDK to upgrade with different functionalities and the newest tools.
  • Slower Build: While Kotlin is speedier than Java in terms of progressive builds, however, it becomes slow when it integrates a full build. This is because Kotlin has more expressive syntax than Java, resulting in slower compilation.
  • Cannot Replace Java: Undoubtedly, Java and Kotlin are similar so it’s hard to distinguish between the two. Still, both have a thin line difference while shifting from one platform to another, especially from Kotlin to Java. In that view, you need to hire Kotlin app developers in such cases.
  • Limited Community Support: Since it has been only a few years post-launch of Kotlin, its community will take time to extend its resources and simultaneously its developers for knowledge growth.

What are the Pros of React Native Platform

  • Hot Reloading: One of the top features of React Native is hot reloading which allows developers to track code changes instantly. This speeds up the development process and facilitates quicker iterations.
  • Large Community and Ecosystem: React Native was introduced in 2015. Since it has been years, it has had large community support and an extensive ecosystem, consisting of several libraries, components, and resources, making development more efficient for various functionalities.
  • Performance: Due to effective connectivity between JavaScript and native layers, React Native fastens the performance by allowing the developers to modify codes under the UI/UX layers. Hence, this is also one of the use cases of React Native.

What are the Cons of React Native Platform

  • Performance Limitations: While React Native offers good performance for most use cases, complex animations, and heavy computational tasks may not perform as well as fully native solutions.
  • Platform Dependencies: React Native is highly suitable for native app development. However, as it utilizes third-party plugins and requires accessibility from other sources, these dependencies complicate the logic codes.
  • Learning Curve: Despite being introduced years ago, it needs a strong knowledge of basic JavaScript and React Native combined. Hence, it is considered to have a steep learning curve.
  • Limited Access to Device Features: React Native may have extensive community support, resources, and libraries, still, it is not compatible with some feature-specific devices to provide efficient native-like functionality.
