ReactJS Vs React Native

Amazing user experiences are created by React using the Virtual DOM, while React Native renders UI components that can be reused on both the Android and iOS platforms by utilising APIs.

Virtual DOM for ReactJs

Document Object Model (DOM), a crucial programming interface that represents a web document and its content, is used in Virtual DOM for ReactJs. The final way libraries and frameworks are utilised and displayed is greatly influenced by their ability to control the DOM.

For React, virtual DOM is a game-changer. It is an electronic rendition of the actual DOM. It implies that while designing dynamic UIs, Virtual DOM manages rapid updates. The major distinction is that Virtual DOM updates outperform Real DOM updates in terms of speed, performance, and user experience.

React Native Native APIs

Additionally, React Native renders UI components using native Application Program Interface (API), Objective-C-written iOS components, and Java APIs for Android components.

Following that, JavaScript is utilised to generate the remaining code and tailor the app for each platform, enabling maximal component reusability and code shareability.

ReactJs makes use of CSS and HTML, whereas React Native does not. As a result, to style the React Native components, JavaScript style sheets are required. But even though it resembles CSS, it is not the same.

Similarly, in React Native, ReactJS uses<p> against <text>, while <div> is used in React instead of <view> for React Native.

Let’s give you a real-time example here:

For ReactJs:

function tick()
{
const element = (
<div>
<p> Hello World </p>
</div>
ReactDom.render(element, document.getElementById(‘root’));
}
setInterval (tick,1000);

For React Native:

import React, { component } from ‘react’;
import {text, view} from “react-native”;
export default class HelloWorldApp extends component
{
render()
{
return
{
<view>
<text> Hello World </text>
</view>
}
}
}

Useful Tip: To run a React Native app, you have to have an Android Studio for Android or Xcode for iOS in your system. Thereafter, you can decide whether you have to run an application on the simulator or directly on the device.

Differences between React JS and React Native

The biggest error our business made was relying too heavily on HTML rather than native. Marc Zuckerberg

As we all know, most siblings share similar qualities and functions. They will acknowledge, though, that their contrasts outnumber their commonalities.

React and React Native are siblings, and the same notion holds true for them. So let’s examine how React and React Native vary from one another.

1) Installation Procedures

React

React is a JavaScript library, as we learned before in this essay. The only thing you need to do is incorporate the React library into the HTML page in the script tag.

<script src="https://unpkg.com/react@16/umd/react.development.js"<crossorigin></script>

<scriptsrc="https://unpkg.com/react-dom@16/umd/react-dom.development.js"<crossorigin></script>

The first React component you make can now be integrated into your HTML website.

Bundler can be used to manage big projects. Webpack may already be set up to bundle to your application if you utilise tools for new projects like Next.Js, the create-react-app command, or the Gatsby framework. You must make sure that Webpack is configured if not.

Bundlers assemble all files with code into a solitary, sizable file. Other bundlers, such as Rollup or Browserify, are also available.

React Native

You need a programming environment like Android Studio for Android or Xcode for iOS in order to create an app utilising React Native.

Other tools, such as Node, the React Native CLI, JSDK Watchman, etc., must be installed, nevertheless. Following installation, you may start a new project with the React Native Command Line Interface and run it on real mobile devices or an emulator.

React JS to React Native conversion is a relatively simple process. In fact, if you are familiar with the JavaScript and React libraries, you will quickly grasp how the React Native framework works. You can create your first native application in this manner.

2) Effectiveness

React

ReactJs is the ideal library if you want to create an outstanding user interface for your project. ReactJs’s ability to run on the client side while being rendered on the server side is one of its outstanding characteristics.

ReactJS increases developer productivity while also providing them with more tools for developing core abstractions. It’s useful for both lower-level items like clickable buttons and higher-level elements like dropdowns, to put it briefly.

Native React

To maximise a developer’s efficiency, React Native uses a distinct strategy. React JS has analogues for the components you may use in iOS and Android to achieve a comparable look and experience. React Native’s building blocks are reusable native components. These parts are directly compiled into native code. Therefore, the app will have the amazing look, feel, functionality, and speed of a native app, distinguishing React native from other mobile app development frameworks.

3) Technology Foundation

React:

Just a JavaScript library, React. So all you need to do to master ReactJs is learn and comprehend JavaScript. You can quickly learn how to use technical documents and work as a React developer.

React focuses on creating user-friendly web user interfaces using JavaScript.

React Native:

React.Js is a framework that is used to build mobile user interfaces using React Native. Since it employs declarative components like React and inherits all of ReactJs’ functionalities, it has several benefits.

React Native is specifically not a JavaScript framework. Java, Objective-C, Objective-C++, and C++ code are all included. As a result, it’s crucial to understand and be proficient in the languages used to create React Native applications.

4) Feasibility

React:

React, also referred to as React JS, combines JavaScript and HTML technology. It has been found that this is mostly done to incorporate CSS, which removes a number of CSS development-related difficulties such global namespace and variable/scope isolation.

React Native:

Do you want to expand the functionality of your current app without changing the entire code? React Native can be useful in this situation.

You can incorporate different native components into your existing app code using React Native. If you used Ionic and Cordova to create your hybrid app, you may reuse the Ionic-based code with just a plugin integration.

5) Compatibility

React:

React JS uses Node to render on the user’s server and was developed with Search Engine Optimization (SEO) in mind.

React Native:

Additionally, React Native is specifically made for creating mobile user interfaces. It implies that React Native functions more like a JavaScript library than a framework, aside from being totally UI-driven. The UI is highly responsive as a result, making the apps feel smoother and load more quickly.
