ReactJS and React Native are chart-topping tools for mobile and web app development. Both look similar, with different suffix names attached to them. Do not get confused over the terms; they both are pretty different from each other. React.js is a JavaScript library with the help of reusable components used to build user interfaces. On the other hand, React Native, with the help of a single code used to create mobile apps for iOS and Android platforms. 

These tools have gained massive popularity due to their ability to develop complex apps quickly. Top fortune 500 companies like Netflix, Airbnb, Instagram, and Facebook used React Native and React.js for development. In this article, we will cover all the required detail to know what these two means and the difference between the two. Also will discuss the advantages of using these two over other frameworks. So, let’s get started!

Overview of React.Js 

react js

So what exactly is Reactjs? It can be known by any of these three names React, ReactJS, or React.js. It is a popular javascript library with a strong foundation and a massive community behind it that is used to create user interfaces or UI components. However, it is used primarily for Web Development. It is used for handling web and mobile app view layers. It is developed to simplify the work of an easy user interface. Before React, JavaScript was used in development, but you must create the same elements multiple times if you have to put it repeatedly. Some popular apps built on React are Instagram, Netflix, Whatsapp, The New York Times, and Dropbox. 

Essential Features of React.Js 

1. Jsx – Java Script Extension

differs from writing the React document in Javascript and JSX. JSX is the syntax extension to JavaScript. With the help of this, we can write the HTML code in the same file that contains JavaScript code. 

2. Unidirectional Data Flow and Flux

React can only work on the downstream flowing data; if the data has to flow in any other direction, then it needs additional features. 

3. Extensions

For application architecture, React supports various extensions. Server-side rendering, Redux is extensively in web development, and React also endorses Flux. 

4. Debugging

Due to extensive community support testing, the react is easy. Facebook provides a tiny browser extension that makes React debugging faster and easier. 

Use Cases of React.Js 

ReactJS is a popular JavaScript library used for building user interfaces. It’s often used to create complex, interactive applications for web and mobile devices. 

Here Are Some Use Cases for React Js:

1. Single Page Applications( SPAs)

Building SPAs that dynamically update UI in real-time Reactjs is used without reloading the page. 

2. Ecommerce Websites

creating ecommerce websites that have interactive features and require real-time updates that can be used. 

3. Social Media Platforms

To create engaging and interactive user interfaces for liking, sharing, and commenting on content. 

4. Enterprise Applications

This can also be used to develop a large-scale enterprise app with reusable UI components that can be shared across the platform. 

Advantages & Disadvantages of Reactjs 

S.NO Advantages Disadvantages
1Declarative Programming – It allows us to describe the user interface declaratively. Development Pace – The developers must constantly relearn how to work in React.js, which becomes hard to keep up with. 
2Component-based Architecture- This makes it easy to build complex user interfaces by breaking them down into smaller, reusable pieces.Lack of Documentation- There is insufficient written documentation due to the number of new releases and updates. 
3Virtual DOM-  Using this allows it to render updates more efficiently than traditional DOM manipulation techniques.Non- Vigilant Focus on User Interface- more tools have to apply for creating functional applications that will cover other parts like data storage and backend. 
4Large Ecosystem- React has a large and active ecosystem, which means many third-party libraries, tools, and resources are available for developers.JSX as a Barrier- it is challenging to grasp JSX code for some web developers. 
5Clean Abstraction- React doesn’t bother with its complex internal functions.  Incomplete Tooling Set- to build a fast, beautiful, and compatible UI after using React for development, you still need to choose a framework. 

Syntax Structure of React Js:

In React JS, the basic syntax structure typically involves creating a component using JavaScript code, and then rendering that component onto the web page using JSX syntax.

Here Is an Example of A Basic React Component:

import React from 'react';

function MyComponent() {
  return (
      <h1>Hello, World!</h1>
      <p>This is my first React component.</p>

export default MyComponent;

Overview of React Native 

react native

It was launched in 2015 and is an open-source framework that Facebook developed. To create native mobile applications for various platforms such as iOS, Android, and Windows, it is one of the best libraries. It has reusable components that can be used to run on multiple platforms. For base abstraction, React native uses Reactjs, but the library components are different, making it another developmental framework. Around 25,000 applications around the world use it. Some popular apps using this are Instagram, Facebook ads, Walmart, Bloomberg, and SoundCloud. 

Key Features of React Native

1. Cross-Platform Functionality

It is used to develop cross-platform mobile applications and build applications for Android and iOS. Using a single language to create different platforms can be a good option, so it is a good option for developers. 

2. Flexible Architecture

In React Native, “Flexible Architecture” refers to the ability to build and customize the app’s architecture according to the project’s specific needs. It allows developers to choose from various tools, libraries, and patterns to create scalable and maintainable applications.

3. Reusable Components

In React Native, “Reusable Components” refers to the ability to create modular UI components that can be reused across different screens or even different applications. Reusable components are essential to building scalable and maintainable applications since they promote code reuse and reduce duplication.

4. Interactive & Customizable UI 

In React Native, “Interactive and Customizable UI” refers to the ability to create dynamic and engaging user interfaces that are both interactive and highly customizable.

Advantages & Disadvantages of React Native

S.NO Advantages Disadvantages
