React Native is an open-source, Facebook-powered technology that allows you to develop cross-platform applications using JavaScript.

With React Native, you can develop an application once and run it on both Android and iOS operating systems—is this fantastic?

What Is React Native?

React Native is a JavaScript framework that is revolutionizing the building of cross-platform applications. Even though the applications are built using JavaScript, they will exhibit the native features of Android and iOS mobile devices.

This implies that the application will display the look, the feel, and the capabilities inherent to the native mobile environment. React Native applications are real mobile applications.

The user interface of React Native applications does not show any significant variations from the native platform applications built using Swift or Java. To achieve this, the business logic for the cross-platform capabilities are bridged to JavaScript.

React Native uses the same model as React, which allows you to construct robust mobile user interfaces using declarative components.

import React, { Component } from 'react';
import { Text, View } from 'react-native';


class LearningReactNativeIsGreat extends Component {
  render() {
return (

    <View>
  <Text>
  Instead of using web components as building blocks, just like React,
  React Native uses native components.
  </Text>
  <Text>
  With React Native, just use native components such as 'View' and 'Text',
  rather than web components such as 'div' and 'span'.
  Got it?
  </Text>
  </View>
);
  }
}

React Native is already powering several popular mobile applications, including Facebook, Instagram, Skype, Tesla, and Walmart.

With a vibrant community around this technology, it’s continuing to evolve and reach new frontiers.

Why should you be left behind?

Benefits of React Native

1. Ease of Learning

Before beginning to work with React Native, you only need to have JavaScript knowledge. Furthermore, React Native is devoid of complicated syntax details, which typifies several other development scenarios. As such, it’s a very beginner-friendly framework.

Native mobile app development tends to be complicated and difficult to grasp. The imperative coding technique intrinsic to Swift, Java, or Objective-C will mean that a single error may cause the entire application to collapse.

However, React Native has a declarative coding technique (inherent to the good-old HTML), which is easier to grasp and implement in mobile app development.

Therefore, if you want to learn how to build cross-platform mobile applications easily and quickly, then React Native will be of significant help.

2. Supports Cross-Platform Mobile App Development

Traditionally, building an application that can work both on iOS and Android devices require two applications to be developed separately. However, with the introduction of React Native, that cumbersome process is no longer necessary.

After learning React Native, you’ll be able to write code in one programming language and deploy your application across multiple mobile platforms. Is that cool?

How will this benefit you? You will save a lot of development time, production costs, and maintenance costs. Simply, you’ll not need to do the same task twice.

In fact, developers who use React Native have reported more than 30% reduction in mobile app development costs.

3. Ability to Integrate Native Code

If you intend to optimize some features of your mobile application using native code, you can easily include them in React Native. The framework integrates comfortably with components developed using Java, Swift, or Objective-C.

It’s also possible to develop a section of your application in React Native and another section in native code—just like the Facebook application.

Here is a code sample.

import React, { Component } from 'react';
import { Text, View } from 'react-native';
import { IncludeNativeCodeComponent } from './my-great-native-code';


class BuildMobileApp extends Component {
  render() {
return (

  <View>
  <IncludeNativeCodeComponent />
  <Text>
  IncludeNativeCodeComponent could use any native code without
  impairing development.
  </Text>
  </View>
);
  }
}

4. Accelerated Debugging

Every developer hates when a program takes long to compile during development or debugging. React Native addresses this problem with the assistance of hot reloading and live reloading features.

Hot reloading refreshes the code that has just been modified. And, live reloading refreshes the whole application whenever changes are detected.

The concept is to maintain the present state of the app while including the code that has been changed during execution—all without requiring recompilation.

This process usually takes less than second, in most situations, something which greatly accelerates the debugging process.

Conclusion

React Native is increasingly becoming popular as the go-to-framework for developing world-class mobile applications.

Therefore, learning about this wonderful technology is what you need to build powerful cross-platform mobile apps.

All the best with your next mobile app!
