2. INTRODUCTION
• The level of competition for cross-platform app development appears to be exceeding an
order of magnitude higher.
• And beyond any doubt, React Native has been recognized as the most preferred cross-
platform solution for building both Android and iOS apps respectively. With React Native,
you can work on two different operating systems using the same platform.
• React Native is an open-source framework developed by Facebook that lets you build native
mobile applications using the JavaScript programming language.
• You can develop apps using React Native while employing Java or Kotlin for Android and
Objective-C or Swift for iOS.

3. • React Native also proves helpful in creating attractive user interface which cannot be
separated from any native app.
• React Native may be a popular choice, but it is not the best option as it also has some
drawbacks.
• Therefore, we will highlight the major pros and cons of React Native, to give you an idea
of ​​when to use the platform and when to avoid it.

4. THE BENEFITS OF REACT NATIVE
• Undoubtedly, React Native is a real asset when it comes to improving performance through
native controls and modules.
• React Native ties into the native components for both operating systems and generates a code
to native API upfront and free.
• Now the performance increases due to the fact that it uses different threads from UI and
native API. You can also choose other options such as choosing WebView, but this will
reduce the performance level.
1. KNOWN FOR OPTIMAL PERFORMANCE

5. • One of the biggest benefits you can get from React Native is the benefit of code reusability.
Developers feel blessed and grateful for Facebook because they don't need to develop a
separate mobile app for each platform.
• In fact, you integrate 90% of the native framework to reuse code for both OSes.
• It is because of this unique feature that developers save a lot of time and also reduce the cost
of app development.
• It's worth noting that you can reuse web application code to build a mobile app if it's written
in React.
2. CAN REUSE THE CODES AND PRE-DEVELOPED COMPONENTS

6. • React Native also accelerates the pace of development due to the presence of pre-developed
components available in the open-source library.
• It simply means that the codes are already written already and you need to implement it as
per the requirements of the app. You are absolutely free to use it.
3. LARGE COMMUNITY OF DEVELOPERS
• The Fact That React Native is an open-source JavaScript platform where every developer is
free to contribute to the framework and it is readily available to all. So, you can take full
advantage of community driven technology.
• This means that if a developer gets stuck somewhere while developing the app, he is free to
take the help of the community members who will guide him in this regard.

7. • The support of a large community is also useful as it allows you to share your experiences
and portfolio so that you can go for better coding.
• One platform is the GitHub React Native community, which encourages developers to share
their experiences when they learn something new about React Native. They also receive
feedback and reviews on establishing better communication with the members of the
community.
• Don't forget that React Native is introduced by the king of social media, Facebook. So, you
will get extended support from the social media giant as well.
• Indeed, Facebook has created a special platform to help developers start long conversations
where you can share your issues and best practices.

8. • React Native is known to support live and hot reloading. Do not get confused as both are
different characteristics.
• If we talk about live reloading then it is a tool that helps in compiling and reading the file
where developer made changes. It also provides a new file for the stimulator, having the app
read it automatically from the beginning.
• Hot reloading is based on Hot Module Replacement (HMR) and started after the initial
reloading process. Although there is not much difference between functions and features, but
the main aspect comes in handy while saving changes.
4. ADVANTAGE OF LIVE AND HOT RELOADING

9. • HMR Inter-mediator will keep the updated files at the specific location even if the app is still
running. The major plus point of Hot Reading is that it allows modification of the source
code and as such, you do not need to recompile the app to view the code.
• Thus, if you have a few open windows including the code and app screens, you will be able
to see the results immediately after making changes to the code. In fact, hot reading also
plays an important role in reducing the waiting time for changes.

10. • We have already discussed in the earlier paragraphs how code in React Native helps in
reducing the cost of reusable app development.
• Developers do not need to use different code for both the platforms as both the OS can be
coded with a single programming language.
• Now, this makes your project cost more economical as you do not need to hire a large team
and different developers to complete the work.
• This is another advantage of React Native as a small team size is enough to complete the
task. Developers gave in-depth experience and established better communication with each
other.
5. REACT NATIVE IS A COST EFFECTIVE SOLUTION

11. • React Native also provides a simplified mobile user interface, which is why it is known as an
open-source JavaScript library rather than being a framework.
• If you have developed a perfect app, it is important to get the sequence right, and React
Native is the best option to achieve this. It provides more responsive UI design and also
reduces loading times.
6. OFFERS SIMPLE USER INTERFACE
7. SUPPORT FOR THIRD-PARTY PLUGINS
• React Native also provides its support for third party plugins which offer some options which
include native modules and JavaScript modules. This is because it does not have some
components in the main framework.
• For example, if you're implementing a map in your app, React Native lets you do this by
linking the plugin to a native or third-party module.

12. • React Native provides one of those features or benefits which is simplifying the process of
data binding. It is because of this aspect that your apps become more stable and the level of
reliability also increases.
• The child element has no effect on the parent data. React Native allows updating only
allowed components and if you have to make any modifications, you need to change and
apply the update.
8. OFFERS MORE STABLE APPS

13. • Modular programming helps to separate the functions of the program into various different
free and interchangeable blocks known as modules.
• Now it is software technology that makes development more flexible and better coordinate
with each other to get updates.
• React Native benefits to achieve this intuitive modular architecture, which helps React
Native developers to easily upgrade apps at an accelerated pace. You can also reuse modules
similar to the code for Web and Mobile APIs.
9. MODULAR ARCHITECTURE

14. • React Native gives you the advantage of having the best list of ready-made solutions and
libraries to simplify the task of mobile app development.
• It also has a large number of libraries which are very useful for developers. For example,
developers can create error-free code while testing a library.
10. PROVIDING HANDY SOLUTIONS AND LIBRARIES
THE CONS OF REACT NATIVE
We have discussed why React Native is a popular choice for developers due to its advantages.
However, without any bias, we need to look at the other side of the coin as well. Yes, now let's
look at some of its major disadvantages:

15. React Native is newbie as compared to other Android and iOS programming languages. It is
still in its repair phase and it may have negative impact on apps.
• One of the areas where it is lacking is with regards to the release of frequent updates, which
is confusing for developers at times. This is because every time a new update is released,
developers have to make a lot of changes and upgrade regularly. There were a lot of
difficulties in upgrading the popular app Airbnb.
• Second, developers sometimes need to write additional native code for components that are
not compatible with React Native, in addition to simply writing code.
• Sometimes, React Native components fail when compared to native components. It is very
difficult to integrate long and huge list with React Native.
1. REACT NATIVE IS STILL NEW AND IMMATURE

16. • React Native can be a tough rope to learn especially if you are just a fresher in the field of
app development.
• This is due to the presence of JSX in JavaScript syntax extensions where HTML elements
are joined with JavaScript. An average learner will not find it that easy as compared to other
cross-platform apps.
2. LEARNING THE ROPE IS A TOUGH ASK
3. IT LACKS THE SECURITY ROBUSTNESS
• We know that React Native is a JavaScript library and open-source framework that creates a
gap in security robustness.
• But sometimes, you need to provide extra security, especially if you are building banking and
financial apps where data is highly confidential. Hence, in such cases, experts recommend
not opting for React Native.

17. • The problem with React Native is that even for high-tech gadgets and devices, it takes a long
time to initialize the runtime before it can be initially rendered.
• This is again because of the JavaScript thread which takes time to initialize.
4. TAKES MORE TIME TO INITIALIZE
5. MANAGING THE MEMORY
• React Native is not suitable to be used for computing intensive apps and yet, the
responsibility of this shortcoming falls on JavaScript.
• It becomes difficult to manage memory and usage due to float computations which are dealt
with inefficiently.
