React native review: Everything you should know in 2021

Nowadays, technology is becoming hotter and hotter. Like any other platform, technology has both advantages and disadvantages. Not only that, it also should not be used to complete every single project. Therefore, we’re seeing an increasing number of developers (even native ones) choose React Native as their main mobile development tool. However, developers aren’t the only ones who make this decision. Therefore, thanks to numerous business benefits such as excellent performance, minimal production and maintenance costs, and more, it’s no surprise that many of the market’s large businesses are adopting React Native as well. So, what makes it so unique for both developers and businesses? Thus, now together with ArowHiTech, let’s take a closer look at the React native review

What is React native?

React native review

Before going deeper into React native review, you must know what React Native is. In fact, React native (also known as RN) is a popular JavaScript-based mobile app framework that lets you create native-looking iOS and Android apps. Using the framework, you may construct applications for a variety of platforms with the same codebase. Furthermore, Facebook launched React Native as an open-source project for the first time in 2015. However, it quickly became one of the most popular mobile development tools. Additionally, some of the world’s most popular mobile apps, such as Skype, Facebook, and Instagram, also use React Native development

When should you use React Native?

Continuing the topic of React native review, you should also explore when you should use RN. All app developers who want their apps to function on all devices, including Android and iOS, while using a single codebase. Therefore, they will use React Native. Although React Native is becoming better and better, there are still a number of issues to be aware of.

Native mobile apps and Cross-platform 

The main distinction between cross-platform and native apps is that native apps are designed to run on a specific operating system. Although cross-platform apps are designed to run across multiple platforms, they lack the flexibility and efficiency on a particular operating system as native apps.

For example: Take an alligator and a fish and put them together. Even if an alligator can walk and swim, it will never be able to swim as well as a fish. On the other hand, fish are unable to walk at all. As a result, cross-platform programs are similar to alligators. Because they can walk and swim, but not swimming as well as fish (native apps).

Therefore, you should compare cross-platform apps and native apps more closely before deciding which one to use. Because Native apps are still unconquered when it comes to performance. However, React Native is quietly catching up.

Pros – react native review

1. Building Time is Reduced

The first advantage of RN in the topic of React native review is it reduces the building time. The reduced development time is React Native’s main selling feature. The framework comes with a number of ready-to-use components that can help speed up the process. However, some solutions are currently missing in React Native. So you’ll have to create them from scratch. But RN is built on JavaScript, which offers you accessibility to the world’s largest package ecosystem. Therefore, you have access to such a large package library. Thanks to that, it will only become better because of saving a lot of time. 

2. Multiple platforms, one framework

You can reuse the codebase (or just a portion of it) between iOS and Android with React Native. In actuality, depending on how many native modules you utilize in your app, full cross-platform development is available to some extent. Some features will be offered as npm packages, while others may require custom development. But everything will only get better. Because the React Native community actively contributes to the framework’s open source, including new tools. 

Using JavaScript allows you to share your codebase not only between mobile platforms, but also different React web apps. Because the technologies are so similar, the same developers may work on both online and mobile applications.

React Native not only helps reduce development time, it also helps increase the consistency of your app’s business logic across all supported platforms.

3. Quick refresh

Quick Refresh came by the end of 2019. Thanks to that tool, it fixes all of Hot Reloading’s problems and delivers a fantastic developer experience. Therefore , it speeds up both new feature development and bug fixes.

4. Smaller groups

Native development for Android and iOS requires two different teams. It may cause difficult communication between developer collaboration and. As a result, it slows down development. The native Android and iOS teams each have their own projects, and their development speeds and techniques are frequently different. Therefore, two projects can quickly become conflicting. It may result in differences in the app’s functionality, behavior, and look. 

Therefore, if you work with React Native, you’ll almost certainly require a JavaScript developer who can code for both platforms. So apps with more native features will need greater assistance from native developers. Hence, the group will be smaller, easier to manage.

5. Fast application

When it comes to the topic of react native review, many people believe that React Native code can slow down an app’s speed. Although JavaScript isn’t as quick as native code, you won’t notice the difference in most situations.

However, when running both React Native and Swift, we can see that the performance of both apps was quite similar. Because performance differences were small, nearly noticeable to the average user. The framework may be less efficient in more complex applications, but you can easily move some code to a native module.

6. UI that is easier to use

The core of React Native is the creation of a mobile user interface. You’ll need to define a sequence of actions in the app while developing natively. Declarative programming is used by React Native. As a result, identifying issues on the paths a user can take is considerably easier.

7. Used by a large developer community

React Native is an open-source JavaScript platform that lets developers share their experience of the development to everyone. Furthermore, if a developer runs into a difficulty, they can seek help from the community. Besides that, thanks to a large developer community, you also can improve your coding skills. 


When mention to the topic of React native review, aside from of awesome pros, RN also has several cons. Let’s take a look at them below.

1. Issues with compatibility and debugging

Your developers may run into problems with package compatibility or debugging tools. If your developers aren’t React Native experts, this could slow down your development because they spend time fixing.

2. Some custom modules aren’t available

Some components are still missing in React Native. Therefore, you have to start from scratch or try to hack an existing solution. You can finish with three codebases (RN, Android, and iOS) for a component instead of just one when designing custom modules. There may be differences in behavior and appearance between such codebases. Fortunately, these cases do not happen often.

3. Native Developers still want

You are required to have knowledge if you want to implement some native features and modules. More open-source libraries are providing easy access to native platform capabilities as the community grows. However, some advanced features may still require the assistance of iOS and Android developers. Therefore, this could be a problem for small teams whose developers lack native mobile experience.

React native review: Alternatives to React Native


Separate development for native iOS and Android platforms is the most suitable React Native alternative. As mentioned above, two teams will be working on two separate apps. This could lead to inconsistency in the programs, as well as the inability to reuse code. 

Native apps are still the best approach to go if you want your app to truly “feel native” or if you want it to function as well as possible. However, keep in mind the price and time implications.


Flutter is a new mobile application framework released by Google. And now it is the most popular cross-platform alternative to React Native. It’s built on the Dart programming language and offers a unique method to cross-platform functionality. It can give apps designed with the framework amazing performance and a native appearance. Flutter’s community is substantially smaller than that of RN because it is so new.


There are lots of cross-platform mobile development options. Besides that,  NativeScript is a framework that allows web frameworks like Angular and Vue.js to be used to create mobile apps. Xamarin utilizes the C# programming language and converts the code to native controls, just like RN.

Moreover, Ionic is built on displaying an app inside a WebView, which is slower than alternative methods.
