28 Dec 2022

Wheth­er it is about increas­ing brand aware­ness glob­ally or increas­ing sales and rev­en­ue, mobile applic­a­tions are boost­ing busi­nesses to new heights.

The increased demand for mobile applic­a­tions com­pelled com­pan­ies to adopt the latest tech­no­logy. React Nat­ive is one such ReactJS frame­work that is the most pop­u­lar lib­rary for applic­a­tion development.

What’s unique about React Nat­ive app devel­op­ment com­pan­ies is that they use cross-plat­form devel­op­ment to provide ser­vices for both Android and iOS.

In the fol­low­ing art­icle, you will learn about

  • ReactJS and React Native
  • How ReactJS is dif­fer­ent from React Native
  • The fea­tures and bene­fits of React

After read­ing this art­icle, you will be able to decide wisely wheth­er React Nat­ive app devel­op­ment ser­vices are the best option for your company’s mobile applic­a­tion needs or not. 

What Is ReactJS?

ReactJS is an open-source JavaS­cript frame­work developed by Face­book (Meta) that is used to effi­ciently build web applic­a­tions with inter­act­ive UI using less code than tra­di­tion­al vanilla JavaScript.

Jordan Walke, a soft­ware developer at Face­book, cre­ated it. Face­book developed ReactJS in its news­feed area in 2011, but it was made avail­able to the pub­lic in May 2013.

In React, your applic­a­tion com­prises small, reusable com­pon­ents, each con­tain­ing a small piece of HTML code. These com­pon­ents func­tion as build­ing blocks that make it sim­pler to cre­ate com­plex websites.

ReactJS con­trols the view lay­er of the MVC (mod­el-view-con­trol­ler) archi­tec­ture with a DOM-based mech­an­ism to fill or change the HTML DOM. As a res­ult, it is sub­stan­tially faster, as it only changes indi­vidu­al DOM ele­ments instead of the com­plete DOM every time.

What Are The Major Fea­tures Of ReactJS?

ReactJS is quickly exceed­ing oth­er JavaS­cript frame­works in pop­ular­ity among front-end developers because of its out­stand­ing fea­tures, includ­ing those lis­ted below.

  • JSX

JSX is a React exten­sion for JavaS­cript XML and has a syn­tax com­par­able to HTML, which is famil­i­ar to many developers. This HTML-like con­tent can coex­ist with Reactʼs JavaS­cript code thanks to JSX.

Although JSX isnʼt required in React, describ­ing how the UI should look and mak­ing code easi­er to read and com­pre­hend is suggested.

  • Com­pon­ents

Com­pon­ents are the reusable build­ing blocks of React; they are small units of code with logic and control.

A React app is built using mul­tiple com­pon­ents; even if the pro­ject is large-scale and com­plex, a React app can be made using these.

  • Uni­direc­tion­al Data Binding

ReactJS fol­lows uni­direc­tion­al data flow or one-way data bind­ing, accom­plished through the flux pattern. 

Com­pon­ents are cre­ated immut­able and can­not be altered; there­fore, data move­ment in the oth­er dir­ec­tion needs addi­tion­al functionality. 

This uni­direc­tion­al flow makes the applic­a­tion more flex­ible and efficient.

  • Vir­tu­al Doc­u­ment Object Mod­el 

A Vir­tu­al Doc­u­ment Object Manip­u­la­tion (V‑DOM) is a vir­tu­al object of DOM main­tained in React memory whenev­er a DOM update occurs.

The entire UI is rendered inside V‑DOM and com­pared to the pre­vi­ous DOM, and only the DOM objects that vary are changed rather than the DOM as a whole.

This con­serves memory and allows your pro­gram to run and load faster.

  • Exten­sions

React offers sev­er­al exten­sions for applic­a­tion architecture. 

For example, in the devel­op­ment of web applic­a­tions, Redux, Flux, and serv­er-side ren­der­ing are all widely sup­por­ted in React. 

For build­ing mobile apps, React Nat­ive is a well-known frame­work of React that is cross-plat­form com­pat­ible and provides React Nat­ive app devel­op­ment ser­vices for both Android and iOS.

  • Debug­ging

Use of break­points makes debug­ging easi­er. For example, the func­tion­ing of that spe­cif­ic code sec­tion may be checked and eas­ily fixed by set­ting break­points at vari­ous loc­a­tions in the code.

What Are The Key Bene­fits Of ReactJS Devel­op­ment?

React is widely used in indus­tries because it has the fol­low­ing key benefits.

  • Easy To Learn And Use

React app devel­op­ment is simple to learn and use, espe­cially if you come from a JavaS­cript back­ground. There are many tutori­als and art­icles avail­able to help you learn React.

  • Cre­ate a Dynam­ic Web Application

Cre­at­ing a dynam­ic web­site with React is incred­ibly effi­cient since it uses JSX syn­tax, which com­bines HTML-like XML code with JavaS­cript and can be util­ised to devel­op excep­tion­al UI designs.

  • Reusable Com­pon­ents

React uses com­pon­ents to build web­sites; these objects of coded blocks can be used many times to quickly devel­op and main­tain large websites.

  • SEO Friendly

ReactJS fixes the dif­fi­culty that SEO has when using JavaS­cript applications.

React pages execute on the serv­er thanks to vir­tu­al DOM ren­der­ing, and each page loads as a reg­u­lar webpage on the browser dur­ing nav­ig­a­tion. This min­im­ises the need for the browser to deal with heavy JavaScript.

  • Faster Ren­der­ing

The com­plete UI is presen­ted inside V‑DOM and com­pared to the pri­or DOM; only the DOM items that dif­fer are updated, as opposed to the entire DOM, allow­ing your pro­gram to run and load faster.

  • Scope for Test­ing the Codes

With the sup­port of break­points, React allows for pro­ject test­ing and debug­ging. With React, find­ing bugs and errors is simple.

  • A Strong Community

There is a strong com­munity that sup­ports ReactJS, and mil­lions of developers are engaged in and devel­op­ing ReactJS. As a res­ult, you can eas­ily find help and support. 

React is fre­quently used because of its abil­ity to devel­op func­tion­al web apps with fant­ast­ic user inter­faces with less effort and fast coding.

How Is React JS Dif­fer­ent From React Nat­ive? Why Should­nʼt You Con­fuse Between Two?


  • ReactJS is a JavaS­cript library.
  • Mainly used to devel­op web applications.
  • It has a router to nav­ig­ate through web pages.
  • Uses V‑DOM to render using browser code.
  • Uses CSS and JavaS­cript lib­rar­ies for animations.
  • Plat­form-inde­pend­ent and can be executed on all platforms.

React Nat­ive

  • React Nat­ive is a React framework.
  • Used to devel­op cross-plat­form mobile applications.
  • It has a built-in lib­rary to nav­ig­ate through mobile applications.
  • It uses its API to render code for mobile apps.
  • Has built-in lib­rar­ies for animations.
