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.

• 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.

The Benefits of React Native
1. Known for Optimal Performance

• 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.

2. Can Reuse the Codes and Pre-Developed
Components

• 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.

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.

4. Advantage of Live and Hot Reloading

• 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.

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.

5. React Native is a Cost Effective Solution

• 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.

6. Offers Simple User Interface

• 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.

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
8. Offers More Stable Apps

• 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.

13
9. Modular Architecture

• 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.

14
10. Providing Handy Solutions and Libraries

• 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.

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
1. React Native is Still New and Immature

• 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.

16
2. Learning the Rope is a Tough Ask

• 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.

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
4. Takes More Time to Initialize

• 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.

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.
