 What is reactjs  and react native. And you need to learn it!

Hello developers I and Gaurav today we are going to learn what is react native and react js.And why you need to learn it. Let’s begin let’s get started 

Some of my friends are confused between react and react native ?Which one is the better among them?can you reuse reactjs code in react native

Reactjs and React Native  are right now powering some of the most popular and widely used mobile apps and websites

Like facebook ,instagram ,youtube and much more

What is a React ?

Reactjs is a JavaScript library that supports both front-end and server. Furthermore, it can be used to create user interfaces for mobile apps and websites.

ReactJS is an open-source JavaScript library used to build the user interface for Web Applications. 

Feature of react.

1. Easy to Learn and Use: ReactJS is much easier to learn and use. Any developer who comes from a JavaScript background can easily understand and start creating web apps using React.

2. Creating Dynamic Web Applications Becomes Easier: To create a dynamic web application specifically with HTML was tricky, which requires complex coding, but React JS solved that issue and makes it easier. It provides less coding and gives more functionality.

3. Reusable Components: A ReactJS web application is made up of multiple components, and each component has its logic and controls. These components can be reused wherever you need them. The reusable code helps to make your apps easier to develop and maintain.

4. Performance Enhancement: ReactJS improves performance due to virtual DOM. The React Virtual DOM exists entirely in memory and is a representation of the web browser's DOM. Due to this, when we write a React component, we do not write directly to the DOM. Instead, we are writing virtual components that will turn into the DOM, leading to smoother and faster performance.

5. The Support of Handy Tools: ReactJS supports a handy set of tools which make the task of the developers understandable and easier. It also allows you to select particular components and examine and edit their current Props and State.

What is a react  native?

React Native is a cross-platform mobile framework that uses Reactjs for building apps and websites. React Native compiles to native app components enables the programmer to build mobile applications that can run on different platforms such as Windows, Android, iOS in JavaScript.

What’s more, Reactjs is used to build components under React Native, and React Native implements Reactjs under their framework.

Feature of react native.

There are several advantages of React Native for building mobile applications. Some of them are

1. Cross-Platform Usage: It provides the facility of "Learn once write everywhere." It works for both platform Android as well as iOS devices.

2. Class Performance: The code written in React Native are compiled into native code, which enables it for both operating systems as well as it functions in the same way on both the platforms.

3. JavaScript: JavaScript knowledge is used to build native mobile apps.

4. Community: The large community of ReactJS and React Native helps us to find any answer we require.

5. Hot Reloading: Making a few changes in the code of your app will be immediately visible during development. If the business logic is changed, its reflection is live reloaded on screen.

6. Improving with Time: Some features of iOS and Android are still not supported, and the community is always inventing the best practices.

7. Native Components: We will need to write some platform specific code if we want to create native functionality, which is not designed yet.

8. Existence is Uncertain: As Facebook develops this framework, its presence is uncertain since it keeps all the rights to kill off the project anytime. As the popularity of React Native rises, it is unlikely to happen.

React vs react native

While there are several similarities between Reactjs and React Native, however, there are some notable differences as well. Let’s have a look:

• Reactjs can be described as a base derivative of React DOM, for the web platform while React Native is a base derivative in itself, which means that the syntax and workflow remain the same, but components alter.

• Reactjs, eventually, is a JavaScript library, which enables the programmer to create an engaging and high performing UI Layer while React Native is an entire framework for building cross-platform apps, be it web, iOS or Android. 

• In Reactjs, virtual DOM is used to render browser code in Reactjs while in React Native, native APIs are used to render components in mobile.

• The apps developed with Reactjs renders HTML in UI while React Native uses JSX for rendering UI, which is nothing but javascript. 

• CSS is used for creating styling in Reactjs while a stylesheet is used for styling in React Native.

• In Reactjs, the animation is possible, using CSS, just like web development while in React Native, an animated API is used for inducing animation across different components of the React Native application.

• If the need is to build a high performing, dynamic, and responsive UI for web interfaces, then Reactjs is the best option while if the need is to give mobile apps a truly native feeling, then React Native is the best option.

SNo.	React	React Native
1	The ReactJS initial release was in 2013.	The React Native initial release was in 2015.
2	It is used for developing web applications.	It is used for developing mobile applications.
3	It can be executed on all platforms	It is not platform independent. It takes more effort to be executed on all platforms
4	It uses a JavaScript library and CSS for animations.	It comes with built-in animation libraries.
5	It uses React-router for navigating web pages.	It has a built-in Navigator library for navigating mobile applications.
6	It uses HTML tags.	It does not use HTML tags.
7	It can use code components, which saves a lot of valuable time.	It can reuse React Native UI components & modules which allow hybrid apps to render natively.
8	It provides high security.	It provides low security in comparison to ReactJS.
9	In this, the Virtual DOM renders the browser code.	In this, Native uses its API to render code for mobile applications.
