Introduction of React Native. What is React Native and why to use the React Native?

React V/s React Native – Difference Between React and React Native

This post is all about React V/s React Native. First of all, we will understand what they are and what are the differences between them.

Jordan Walke and his team from Facebook released the React JS library in 2011. Dynamic and high performing User Interface(UI) was the goal to develop React.js.

A JavaScript library which brought together the speed of JavaScript and a new way of rendering pages, leading to responsive and dynamic user input. Two years after the team Open Sourced React.js they also released React Native in 2015.

React.js (React or ReactJS)

A JavaScript library which is responsible for building a hierarchy of UI components. In other words, we can say which responsible for the rendering of UI components. Provides support for both frontend and server-side. Remember, React.js is just the V part of the MVC framework, a library meant for rendering your views.

React Native

A framework for building native applications using JavaScript, so you can say that it does not run the HTML code with JS in web view using native web APIs so it is not a hybrid app development platform. It compiles to native app components, which makes it possible for you to build native mobile applications.

React V/s React Native

ReactReact Native
React is the base abstraction of React DOM for the web platformReact is the base abstraction so the syntax and workflow remain similar, but the components are different.
A JavaScript library you use for constructing a high performing UI layer.An entire platform allowing you to build native, cross-platform mobile apps.
Browser code in React is rendered through Virtual DOMNative APIs to render components on mobile.
HTML for UI.JSX components for UI.
CSS for Styling.The stylesheet for Styling.
Can do animation with the CSS like normal web development.Have to use the animated API which comes with React Native to animate different components of your application
Ideal for building dynamic, high performing, responsive UI for your web interfacesIt is meant to give your mobile apps a truly native feel

Introduction to The Current Technology – React Native

Introduction to The Current Technology – React Native includes the basic definition and the main concept behind the origin of the React Native. Let’s get started.

Introduction to The Current Technology – React Native

React Native is a JavaScript Framework which is used to build native mobile apps using JavaScript and React. It uses the same design as React and maintained by Facebook and a community of individual developers and companies.

Like, React it lets you compose complex UIs from small and isolated pieces of code called “components”. It is currently one of the most popular JavaScript frameworks.

React Native is very useful to build Android and IOS Apps.

Why React Native?

One thing that should come in our mind is that Cross-platform frameworks like Cordova, PhoneGap, IONIC, and more were already in the industry to build Hybrid apps then why React Native?

To answer this just think what if you could create Cross-Platform Native Mobile Apps using the single JavaScript framework? Amazing Right?

This is the beauty of React Native. With React Native, you don’t build a “mobile web app”, an “HTML5 app”, or a “hybrid app”. You build a real mobile app that’s indistinguishable from an app built using Objective-C or Java.

It uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.

Native Code Integration

You can also add your Native components in React Native which are written in Objective-C, Java, or Swift. It lets you integrate your already written code in React Native and you can further develop the application using React Native.

If you want to optimize a few aspects of your application you can write those sections in Native code and can integrate with React Native App easily. It’s also easy to build part of your app in React Native, and part of your app using the native code directly. Facebook application is the best example of this.

React Native is a component-based language and everything in React Native is a component. For example, one could make a <SocialPost > component that would display a Post heading, Image, Description, comments, the user can submit the comment etc — all just by including one line of code: <SocialPost ></SocialPost>.

The biggest advantage of using components is that you can change any component at any point in time without affecting the rest of the applications. This feature is most effective when implemented with larger applications where data changes frequently.

When we update or change any data, React Native automatically updates the specific component whose state has actually changed. This saves from the task of reloading the whole application to reflect the changes.

Example of the Single Screen with Text using React Native is

We hope we were able to explain what is React Native and why you should use it to develop the Mobile Applications.

Introduction to ReactJs

Introduction to ReactJs includes the basic definition and the main concept behind the origin of the React. So Let’s get started.

ReactJS

React is a declarative, efficient, and flexible JavaScript library for building user interfaces.

ReactJS is maintained by Facebook and a community of individual developers and companies. It lets you compose complex UIs from small and isolated pieces of code called “components”. It is currently one of the most popular JavaScript front-end libraries which has a strong foundation and a large community supporting it.

React can be used as a base in the development of single-page applications or mobile applications. Complex React applications usually require the use of additional libraries for state management, routing, and interaction with an API.

ReactJS is only a frontend library and not the whole framework, which deals with the View component of MVC (Model – View – Controller).

Why ReactJs?

Javascript Frameworks like Angular, Backbone, Ember, and more were already in the industry to manage the view of our application then why React?

The answer is what if you could create your own HTML element that has customized functionality? For example, one could make a <MyHeaderMenu> element that would display a Logo, Heading, Subheading, Search bar input, Navbar menu, run validations on the text typed into the search bar input, submits the form when the user hits the enter key, etc — all just by including one line of code: <MyHeaderMenu></MyHeaderMenu>.

For those of you coming from the Angular world, you can think of React Components as a close analogy to Directives

However, React is capable of becoming an entire replacement for your views because you can nest components. The biggest advantage of using components is that you can change any component at any point in time without affecting the rest of the applications. This feature is most effective when implemented with larger and real-time applications where data changes frequently. When we update or change any data, ReactJS automatically updates the specific component whose state has actually changed. This saves the browser from the task of reloading the whole application to reflect the changes.

Example of the web page entirely rendered using ReactJs can be

So with the help of this small example, we can imagine the scope of ReactJs in industry. We hope we were able to explain what is React and why you should use it.
