What Is The Difference Between React Native and ReactJS

iCrowd Newswire - Oct 5, 2020

Hello everyone! This article is dedicated to those who work or are going to work with JavaScript. Do you know what ReactJS and React Native are? And do you know that they are not similar? Read on, it will be interesting!

Let me remind you, JavaScript language is used by front-end developers, who create User Interface (UI). The User Interface is what you see in the browser when you open any website. Like any programming language, JavaScript has its own framework and its own libraries. Backed by Facebook, Instagram and an established developer community, React is one of the most used JavaScript libraries at the moment. ReactJS Development is in no way like developing mobile apps with React Native, and they serve different purposes. Let me clarify to you all the main differences between these two PLs and provide an approach to choosing the right option for a specific project.

The main distinguishing feature:

ReactJS is a JavaScript library, while React Native is a mobile app development framework. ReactJS is a JavaScript library that helps companies construct stunning UIs. One of the main qualities of React is that it can run on client side and render on server side, and can interact with each other. Therefore, it is widely used to build high-performance web applications and User Interfaces. Whereas React Native is a mobile app development framework that builds mobile apps using ReactJS. It allows you to create an exhaustive mobile User Interface from declarative components. React Native offers features like Hot Reloading to develop apps faster and with less effort.

Both increase the efficiency of development, but in different ways.

ReactJS specializes in its ability to provide a great performance and a fully managed render loop for its components. By simply customizing the distribution, creation, and use of reusable components, it allows developers to have more options to use and create basic abstractions. This turns out to be useful for low-level components such as buttons, as well as higher-level items such as dropdowns. React Native provides the same profits, but with a different approach. React Native blocks are reusable components that are compiled directly into the native environment. The components you’ll be using in Android or iOS have counterparts in React, so you’ll get the same look and feel. This structure provides faster application development. This application will have the view, speed and functionality of its own mobile application and that makes React Native different from other frameworks.

ReactJS uses the Virtual DOM, while React Native uses native APIs.

ReactJS uses virtual DOM to create better UX. Building the DOM takes time because the pages are big today. But, ReactJS gets the job done faster using the virtual DOM. This way, ReactJS uses an abstract copy of the document object model and exposes changes for one component without affecting the rest of the UI. This is what makes ReactJS one of the best solutions for quickly updating and creating dynamic UIs. React Native takes this step earlier. It uses native APIs to render parts of the user interface that can be reused on both iOS and Android platforms. As well as the Java API for rendering Android components and the Objective-C API for writing iOS components. It also uses JavaScript for the rest of the code and customization of the application for each platform. This gives React Native the ability to reuse components and codes.
ReactJS integrates technologies, while React Native code can be combined with any existing application.

React uses HTML and JS, following the rule that they go hand in hand all the time. This idea has been extended with CSS, which eliminates many of the worldwide scope and variable / scoped isolation issues. On the other hand, React Native provides opportunities for companies that want to improve an existing application but don’t want to change the whole thing. You can add React Native components to your existing app code. Or if your current mashup was made with Ionic and Cordova, use that Cordova based code with a plugin.
