reactjs vs react native a comprehensive comparison itechnolabs

Do not dare to call yourself an enthusiast developer if you cannot think of the most sensational thing that happened to the software development world. Please do not if ‘React’ is not the first thing that comes to your mind.

Afterall, React has been doing rounds in the software development arena since its inception in 2011. It is an open-source library which you can readily use for crafting exquisite UI/UX designs for web and mobile apps in no time. However, what may confuse you, especially if you are not a development fanatic and aspiring to build a web or mobile app, is the ReactJS vs. React Native debate.

ReactJS and React Native are two successful descendents of the React line. They enjoy the same level of popularity that has come to the share of React and the numbers clearly state so – 

  • As per Statista, ReactJS is clearly developer’s favourite after NodeJS as more than 40 per cent of the web developers use it to build powerful web applications as of year 2023
  • Again, Statista claimed that React Native is the second preferred choice amongst mobile developers for cross-platform app development after the Google-built Flutter in the year 2022

Do not worry! We will not make you wait more and immediately jump to our impending ReactJS vs. React Native debate. Let us begin. 

What is ReactJS?

Crafted in 2011 by one of Facebook’s tech wizards, named Jordan Walke, ReactJS can never disappoint you. Simply put, it is a library that is open-sourced and has been created using JavaScript programming language. You can use it to create entire websites and user interfaces of the mobile apps.

Obviously, ReactJS is not like any other UI library because it treats a singular user interface (UI) as a harmonious blend of smaller components. These components can be used multiple times on the website in the same or different versions. Consequently, it makes designing and rendering of a user interface quicker and easier.

Of course, names of many big giants pop up when we talk about the web apps created using ReactJS. They are Facebook, Airbnb, Dropbox, Instagram, BBC, and Paypal, to name a few.

Advantages of using ReactJS –

  • Reusable Components –

As ReactJS allows you to reuse the components of the user interface, you avoid building a component from scratch every single time it occurs on the website and save a massive load of your development efforts.

  • Less Coding –

ReactJS makes a strategic use of JavaScript Extension (JSX) that allows you to use shortcuts and make your coding simpler. In addition to that, it take care that you app exhibits higher performance.

  • Easy Usability – 

As ReactJS comes with gigantic loads of tutorials, learning material, and documentation, it becomes easier for any JavaScript developer to learn it. You may start developing interesting web application using ReactJS very soon.

  • SEO Friendly – 

When you build your website by leveraging ReactJS, you automatically enable your website to rate high on the lines of search engine optimisation (SEO). This is because of the server-side rendering and meta tags.

  • Faster Update –

Rather than modifying the actual DOM, you can update virtual DOM when using ReactJS. In this way, you change only the relevant component, and not the entire user interface, making rendering and updation easier.

Disadvantages of using ReactJS

  • Pace of Change –

With a gigantic community of developers at hand, it becomes quite natural that the ReactJS technology improves and evolves at an immense speed with which some developers cannot keep up.

  • Complex Codebase –

Due to its dependence on JavaScript Extension (JSX) and components-based architecture, the code used to build websites can turn complex and may get difficult to maintain and scale.

  • Poor Documentation –

The pace of updating the documentation concerning ReactJS has not been able to match the pace of advancement of ReactJS and has resulted in creating unnecessary hassles for a developer in case a glitch occurs.

Steps to create an Application using Reactjs

Follow the steps given below and get started with your app development process instantly –

  • Obviously, the first and the foremost step is to create a react app installation
  • When you are done with the installation, through a thorough look at the app structure
  • Now is the time to kick off the react app development server
  • After you do so, you can start working on your app and make relevant changes to it
  • When you are done with the app development, it is important to rigorously test it using React testing library
  • After successful testing of the app, you make necessary changes to the app’s metadata
  • You must use asset like images and kickstart installation of dependencies
  • You have to now import essential react components and complete CSS app styling
  • Now is the time to create your react app and deploy it on the chosen platform

What is React Native?

In simpler terms, react native is a cross-platform app development framework that creates mobile apps for both iOS and Android using a single codebase. Invented in 2015 by the one and only Jordan Walke, React Native has been crafted using JavaScript as programming language and JXL as markup language.

React Native framework really is a bridge framework. It acts as a bridge between JavaScript domain and native domain. Through the react native framework bridge, information gets exchanged between the two domains, resulting in the successful execution of functionalities on the mobile app.

The apps built using react native app development services are some of the most trendy apps in the app market. They are Facebook, Instagram, Pinterest, Ubereats, Skype, etc.

  • Code Reusability – 

When you use react native framework, you can use 90 percent of the code created for android app for iOS app and vice-versa, enabling faster development of your app with lesser efforts.

  • Native Look –

When you hire dedicated react native developers and use react native UI components, both the JavaScript and building blocks of native user interface are compiled, rendering a very native look and feel to your mobile app.

  • Large Community –

It is quite evident that the react native framework enjoys quite a huge community of developers. Therefore, if you face a hurdle anytime developing your mobile app using react native, you must know that there is no dearth of support.

  • Rapid Reload –

React native’s live reload feature allows you to witness changes as you make them, which again saves a lot of your time and efforts as you get to reload only those components which needs modification.

  • Cost-Efficiency – 

When you use react native app development services, you need not have to hire two separate development teams as only one react native development team can create apps for both the iOS and android using a single codebase.

Disadvantages of using React Native

  • Debugging Issues – 

If your react native developer do not hold a functional knowledge of programming language of the native code, we are really sorry to inform you that you may face severe difficulties in fixing the bug issues of your react native app.

  • Simple Interface – 

If sophistication lies at the core of your app interface which cannot do without multiple number of advanced functionalities and react native UI components, then react native framework will be of very little use to you and your cross-platform app development.

  • Compatibility Issues – 

The evolution of react native framework is considered slower when compared to rapid advancement in the software of the concerned devices. As a result, your react native developer may have to spend more time in coding in order to dodge compatibility issues.

Difference between ReactJS vs React Native

difference between reactjs vs react native itechnolabs

We are certain that you have gained a vivid understanding of reactJS and react native. However, a comparative analysis of the two will only make things simpler for you. Hence, we present to you below the major differences between reactJS and react native. Please consider reading –

  • Installation – 

For the purpose of installation of reactJS, you will have to use a command line tool named Node Package Manager (NPM).

However, for installing react native, you would not just need a Node Package Manager (NPM), but also a react native command line tool along with an integrated development environment (IDE).

  • Technology – 

We have already apprised you with the knowledge that reactJS is based on the popular programming language named JavaScript. Therefore, if you know JavaScript in and out, you are ready to build powerful web applications via reactJS.

As react native framework utilises reactJS library for the purpose of building mobile app interfaces, your developer has to know JavaScript to use it. However, just JavaScript will not suffice as your developer must possess a functional knowledge of Object – C, Objective – C ++, and C++, which also constitutes react native framework.

  • Rendering – 

For the purpose of rendering web applications built using reactJS, you have to make use of virtual DOM. A virtual DOM is basically a replica of the actual DOM.

However, when mobile apps built via react native framework are concerned, rendering takes place via native APIs so as to cater users with an app interface with more native feel.

  • Syntax – 

As reactJS is based upon the JavaScript programming language, it makes use of HTML syntax. It may also use JavaScript extension for the same purpose.

However, react native framework uses its very own react native syntax that cannot render in HTML at all. Therefore, it cannot be used for building websites.

  • Efficiency – 

As far as reactJS is concerned, web development takes place in a much shorter time frame. Also, as codes can be reused in reactJS, development time further shortens.

However, react native framework enables development of mobile apps that are high-performing in terms of app experience. 

Which one should you choose for your application development: ReactJS vs React Native?

 Now when you know the significant differences between reactJS and react native, it is our duty to assist you to choose between the two keeping in mind your project requirements. Read the following and you will get an instant clarification – 

  • Obviously, for a simple to highly sophisticated web application, your only choice between reactJS and react native app development company is the former.
  • For very sophisticated mobile app interfaces, both reactJS and react native app development services are not a very favourable option
  •  React native framework may not be a good choice if your mobile app will need regular updation. However, reactJS will work
  • Of course, go for react native framework when you aspire to give a rather authentic and native look to your mobile app.
