React Native Introduction

React Native is a framework created by Facebook that enables the development of native-style apps for iOS and Android using JavaScript as the common language. React Native was initially only created by Facebook to support iOS. However, the library can now render mobile UIs for both platforms thanks to its recent support for the Android operating system.


  • HTML, CSS, and JS basics are required.
  • ReactJS basics are required.
  • Your system needs to have NodeJs installed.

React Native development is incredibly effective and immensely addictive, but getting started can be challenging. Your JavaScript code is built using the JavaScript runtime Node.js by React Native.

React vs. React Native

In the simplest terms, React Native uses React, but it isn’t a ‘newer’ version of React.

React, commonly referred to as ReactJS, is a JavaScript library used to create a website’s front end. It was created by the Facebook engineering team, just as React Native.

In the meantime, React Native, which is run by React, enables developers to quickly assemble and launch iOS and Android apps using a set of UI components.

Both React and React Native use JavaScript with a unique markup language called JSX. React and React Native, however, employ different syntax to render elements in JSX components. Additionally, while React Native permits the usage of native mobile user interface elements, React employs some HTML and CSS.

What is Cross-platform development?

Building software that works on multiple types of hardware platforms is known as cross-platform development. Microsoft Windows, Linux, and macOS, or simply two of them, can all be used by a cross-platform programme. A cross-platform programme is one that works the same way on any computer or mobile device, such as a web browser or Adobe Flash.

Characteristics of cross-platform development?

A larger audience

Cross-platform software operates on both platforms, giving you access to a larger user base, so you don’t have to choose between targeting iOS or Android customers as your audience.

Platform uniformity

Due to the common codebase, there are some navigational and design variations between iOS and Android that are automatically addressed in cross-platform development. This makes it easier than if the app were built on native to establish a consistent brand identity across both platforms.

Reusable programme

You may create a single codebase for both Android and iOS at the same time, which is one of the biggest benefits of cross-platform development. Native app development necessitates the production of separate lines of code and frequently demands the services of two independent software engineers, one for iOS and one for Android.

More rapid development

Product development is substantially quicker because there is just one codebase needed to handle iOS and Android, and everything is in one location. Even though they support several devices, cross-platform programmes are created as single projects, allowing for extensive code reuse.

Lower expenses

Thanks to the flexibility to reuse code and speedier development, which directly affects the cost, creating cross-platform applications can be 30% less expensive than creating native apps.

Because of what you’ve read up to this point, you might believe that cross-platform programming is without flaws, but it actually has certain drawbacks. Now let’s begin to discuss them.
