React vs React Native: The Ultimate Key Differences To Check Out

A big confusion exists in the mind about React and React Native and whether both are the same or not.

To clear the confusion about React and React Native, it becomes of prime importance to understand the basic concept of React Vs React Native in detail.

As per the recent survey by Stack Overflow, it has been estimated that ReactJS is the most popular web framework that is used by many developers.

What is React?

React, or ReactJS is an open-source JavaScript library specifically used to build the user interface for Web Applications. It takes sole responsibility for only the view layer of the application.

In addition, we can say that ReactJS is

• A library that typically supports both front-end development and server-based configurations.
• Created by Jordan Walke and his team from Facebook.
• A new way of rendering pages, leading to responsive and dynamic user input.
• Responsible for the rendering of UI components.

React is beneficial for developers working with a reputed ReactJS development company in many ways, including

• Developing fast, adaptive, and intuitive mobile and web applications.
• They can quickly automate the entire design process.
• They are not bound to strict rules; instead, they can work according to their convenience.
• Easily plugins and libraries integrations are made possible with existing code.
• Enables developers to develop fast, scalable, and simple web applications.

Hope you got a clear vision of what is ReactJS. Now, we’ll come across the concept of React Native.

What is React Native?

React-Native is a ReactJS-based framework designed explicitly to develop robust and responsive mobile apps. It is designed to build native mobile applications by utilising reusable components.

Moreover, we can say that React Native is:

• Used to develop rich mobile UI from declarative components using only JavaScript.
• A hybrid mobile app development framework that allows you to build mobile apps only with a single code base.
• A framework that allows building mobile apps natively across different platforms like Android and iOS.

React Native is beneficial for developers working in a React Native App development company in many ways including

• They can use ReactJS for building mobile apps and web applications.
• It allows them to easily compile native app components to build mobile applications that can efficiently run on Android, iOS, and Windows devices.
• The syntax and workflow remain similar to ReactJS, but the components are different.
• The developers can only target mobile platforms rather than web browsers.

Working of React Native Vs React

Now it’s time to explore the working process of the leading technologies: React and React Native. First, let’s start with React framework. To make it concise, ReactJS uses VDOM, while React Native uses API for its working process.

ReactJS’ Virtual DOM

ReactJS typically uses VDOM (Virtual DOM) to create an application’s inspiring user experience (UX). The representation of the web document and its content is done correctly with the help of an external programming interface named DOM.

One effective way to perform DOM management has greatly impacted how libraries and frameworks are used to make the application more secure and robust.

But in the case of React application, Virtual DOM has changed the entire scenario. VDOM is nothing but a visual representation of the real DOM. While creating dynamic UIs for your application, the primary role of the VDOM is to manage quick updates.

What is the importance of virtual DOM as compared to real DOM?

• Speedy
• Enhanced performance
• Better user experience (UX)

React Native’s API

React Native framework utilizes APIs to render robust UI components that play an essential role in Android and iOS applications.

Generally, React Native uses Java APIs to render Android components. While for iOS applications, React Native utilizes native API and Objective-C for rendering UI components.

So, the role of JavaScript is to deal with the remaining available code and personalize the application for every platform (Android or iOS). So, it enables maximum component reusability and code shareability.

For React Native, you need to deal with creating a style sheet in JavaScript just for styling React Native’s components. So, in simple words, we can say that React Native is not leveraging CSS and HTML, but ReactJS is.

If we talk about the coding principle, ReactJS uses tag instead of tag. On the other hand, tag is used in React rather than tag for React Native.

Let’s see the example of ReactJS.

function sampleapp ()
{
const element = (
<div>
<p> Welcome to the World!!! </p>
</div>
ReactDOM.render(element, document.getElementById('root'));
}
setInterval (sampleapp,1000);

Now, see the example of React Native.
import React, { component } from ‘react’;
import {text, view} from “react-native”;

export default class SampleApp extends component
{
render()
{
return 
{
<view>
<text> Welcome to the World!!! </text>
</view>
}
}
}

Advantages of React Native Vs React

After having a basic understanding of React Vs React Native along with its working, it’s time to explore how React and React Native will be helpful to you in creating robust web and mobile applications.

Top Advantages of Using React

• DOM (Document Object Model) is a viewing agreement between data inputs and outputs. It works faster than another conventional full refresh model, as virtual DOM refreshes only parts of the page. Moreover, it plays a vital role in enhancing the performance of web applications.
• With the help of ReactJS, you can effectively use code components multiple times. Such reusable components help you in saving a lot of time in web and mobile application development.
• The applications developed with the ReactJS framework will make your application SEO-friendly. The rendering of your web pages is performed directly from the server to the browser, which eventually improves the SEO of your web app.
• React plays an essential role in the life of developers as it is solely responsible for improving the debugging speed of mobile and web applications.
• React coding standards are very familiar, even for non-familiar users. It often happens that some framework needs you to learn multiple concepts that are only useful within the framework.

Top Advantages of Using React Native

• React Native is vital in improving the application’s performance and is made possible with its Native Modules and Native components. React Native renders specific code components with native APIs, which is not possible with other cross-platform frameworks like Cordova or PhoneGap that typically render code via WebView.
• React Native is a robust framework that usually comes with all the advantages of React.js. As we know, React.js is a master in dealing with providing a better UI, so those benefits remain.
• The excellent part about React Native platform is that the developers don’t have to develop the same application for iOS and Android separately. It’s because they need to reuse the common logic layer directly.
• The component-based structure of React Native platform typically allows developers to build mobile apps by strictly following a more agile, web-style approach to development than most hybrid frameworks and without any web development at all.
• If you have a basic understanding of JavaScript technology, React Native will be easy to learn. Moreover, it allows most front-end web developers to be mobile developers. By knowing JavaScript, platform APIs, some native UI elements, and any other platform-specific design patterns, you can efficiently adopt React Native platform.
• With the help of this robust framework, you do not have to refurbish your old app. Instead, add React Native UI components to your existing app’s code without having to rewrite the entire code. Isn’t it great?
• What’s the primary role of Native app development? Inefficiency, slower time to deployment, and less developer productivity. React Native brings high speed, responsiveness, and agility of web app development along with effectual processing and the best user experience to the hybrid space, to provide your users with a native app experience.

Disadvantages of React VS React Native

After exploring the advantages of React Vs React Native, it’s time to see the drawbacks of both technologies.

Top Disadvantages of Using React

• Complexity of JSX
  React utilizes JSX (JavaScript XML), an extension or plugin that allows the developers to code HTML in React applications. So, it becomes challenging for the developers to prefer JSX documentation, especially for freshers.
• Frequent Library Updates
  With the constant changes in the library for React applications, it becomes pretty difficult for developers to deal with application speed. Moreover, such React improvements are generally occupied by specific libraries and other updates, making the development code less robust.
• Learning Curve
  Compared to React Native, React takes much more time for developers to learn in a short amount of time. In simple words, the learning curve of React is definitely more, making it a challenging factor for new developers to create an application using React UI Frameworks.
• Third-Party Integration
  As we know, React comes up with various third-party plugins and modules, and it possesses only a few native modules. Using third-party integration support makes it challenging for the developers to combine HTML and CSS code directly into JSX, along with its code complexity.
• Overhead Cost & Time
  It becomes of prime importance to download another react-enabled library, and that plays an essential role in increasing overall cost and time overheads. Let’s say you are using the Carbon framework for UI experience; then it becomes crucial to download Carbon components with react.

Top Disadvantages of Using React Native

• Lowers Development Speed
  The development speed of React Native applications lowers as the application is loaded with multiple features and modules. In addition, with the shortage of native modules and third-party libraries dependencies, React Native applications’ development speed is lowered too.
• Constant Updates
  The developers are constantly working on providing better development of React Native applications. So, with such constant updates, it becomes pretty challenging for the developers to deal with new native components, improved performance, and custom components.
• Lacking Native Libraries
  React Native is solely responsible for slowing down the entire development process if your application is bound with multiple heavy functionalities. The primary reason is that it lacks native libraries and is dependent on external, third-party libraries.
• Loosely Held Abstraction Layer
  React Native programmers can easily fetch tags like HTML, stylesheets like CSS, and code from Javascript. And that’s what the loosely held abstraction layer is about. It provides more freedom to the developers, but at the same time, it poses challenges as well.
• Lacking Security Robustness
  React Native is solely responsible for creating a gap in security robustness when you create banking and financial apps where data is highly confidential; experts advise not to choose React Native.

Technical Difference Between React and React Native

It’s time to see the differences between React Vs React Native.

1. Installation Scenario

   As we all know, React is a JS library, so it becomes essential to import or integrate React library into the HTML page.

   Copy

   <script src="https://unpkg.com/react@18/umd/react.development.js" crossorigin></script>
    <script src="https://unpkg.com/react-dom@18/umd/react-dom.development.js" crossorigin></script>

   Likewise, you can start by creating your first components in the ReactJS application.

   On the other hand, to create an app using React Native framework, you must first have Android Studio (for Android applications) and Xcode (for iOS applications) in your system.

   Not only this, you must install other essential tools like Node, React Native CLI, and others depending on your project needs. Once the installation is done, you can start creating new React Native components by using React Native CLI and directly executing it on a mobile emulator.

2. Developer Efficiency

   To design and develop an inspiring User Interface for your application, React is the perfect library for it. The excellent part about ReactJS is that you can efficiently execute code on the client side while still rendering on the server side.

   ReactJS is not only responsible for improving developer efficiency, but it allows you to deal with more specific options required to opt for making fundamental abstractions.

   While React Native systematically adopt a slightly different approach with an aim to enhance the performance of the developer’s efficiency. The fundamental building blocks of React Native applications are the reusable native components, and such components are directly compiled into native code.

   With the help of the React Native components, your application gets a fantastic look and feel of responsive functionality, and, most importantly, speed is enhanced.

3. Technology Basics

   As React is a JavaScript-based framework, it’s quite apparent that you must have a basic knowledge of JavaScript technology. However, if you have good expertise in JavaScript, you can easily become a ReactJS developer in a short period.

   React Native is a framework that typically utilizes ReactJS to develop mobile user interfaces on a large scale. But, as React Native is not a pure JavaScript framework, combining Java, Objective-C, Objective-C++, and C++ code is mandatory for you to learn this framework.

4. Achievability

   React is a framework that typically combines HTML and CSS for designing and building robust web applications. Moreover, it’s possible to integrate CSS, eliminating multiple challenges associated with CSS development.

   React Native help you add additional components and features to the existing applications without making drastic changes in the coding. For example, let’s say your mobile application is created using a hybrid framework like Ionic and Cordova. It becomes easy for you to reuse that Ionic-based code smoothly with simple plugin integrations.

5. Syntax

   Remember that React Native is not concerned with HTML-like syntax, so creating a web application using React Native is impossible.

6. SEO-Friendly Application

   While developing a ReactJS application, you must consider SEO parameters. The primary reason behind SEO perspectives is to rank among the top in the leading search engines.

   ReactJS comes up with multiple tools and libraries that easily optimize your applications in terms of search engine optimization (SEO).

   But, in the case of React Native, you do not have to deal with SEO. So it ultimately depends on how we build native UIs for our application needs.
