ReactJS vs React Native

ReactJS and React Native are two well-known technologies that have attracted a lot of interest in the quickly developing field of online and mobile application development. Although both technologies are well known for their ability to create user interfaces, they are specifically targeted for web frontend and mobile app development, respectively. We will examine the finer points of both technologies, offer code examples, and clarify their primary distinctions and uses in this extensive post.

ReactJS: A Frontend Powerhouse


The main purpose of the open-source JavaScript package ReactJS is to create user interfaces for online applications. It is one of the most well-liked options among front-end developers because it was created and is maintained by Facebook. The Virtual DOM, ReactJS’s effective rendering system, is its main competitive advantage since it reduces the need for costly updates to the actual DOM.

Coding Example

Let’s take a look at a simple ReactJS component:

import React from 'react';

const MyComponent = () => {
  return <div>Hello, ReactJS!</div>;

export default MyComponent;

Key Elements

Initial Component-Based Architecture

ReactJS’s component-based design encourages a modular approach to UI development. Codebases are made cleaner and easier to maintain since components are reusable and contain their own logic.

Declaration Syntax

ReactJS is a declarative vocabulary that enables developers to specify the appearance of a user interface depending on its state. This method makes it simpler to comprehend and analyze the behavior of the program.

Virtual DOM

The Virtual DOM in ReactJS makes updates more effective by only rendering the UI elements that have changed. This boosts efficiency and guarantees a positive user experience.

React Native: Facilitating the Development of Mobile Apps


A ReactJS plugin created exclusively for creating mobile apps is called React Native. React Native, in contrast to conventional cross-platform solutions, makes use of native components to give a genuinely native appearance and feel across a variety of devices.

Example of Coding

The following React Native component makes a straightforward text view:

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

const MyComponent = () => {
  return (
      <Text>Hello, React Native!</Text>

export default MyComponent;

Key Elements

First-person Performance

React Native allows programmers to write JavaScript code while still attaining native-level performance, thereby bridging the gap between web and mobile development. Due to the mapping of React Native components to their native versions, this is feasible.

Hot Reloading

Hot reloading is a handy feature for developers using React Native. This function cuts down on development time by letting you view changes in the app right away as you make changes to the code.

Third-Party Platform Usability

Developers can create code once using React Native and deploy it to both the iOS and Android platforms. Because of this, development work is significantly reduced and device uniformity is guaranteed.

ReactJS or React Native?

The nature of your project ultimately determines whether you should use ReactJS or React Native. ReactJS is a great option if you want to create dynamic online user interfaces. React Native, on the other hand, is the way to go if you’re starting a mobile app development project and want to achieve native performance and cross-platform reusability.

In this article, we’ve examined the distinctive qualities of both technologies and given code examples to show how they may be used. You may make an informed choice that is in line with the objectives and specifications of your project by being aware of the advantages of ReactJS and React Native.
