Introduction of React JS and React Native with Features

What is React JS?

React is the most popular front-end, declarative, flexible and efficient JavaScript Library in the web development field to build fast and interactive user interfaces. It is mainly used by big and established companies as well as some startup companies including Airbnb, Netflix, New York Times, Instagrams etc. The addition of lots of features in React makes it better than any other frameworks as compare to Angular.JS. It is a component-based, open-source, front-end library which is responsible for the View layer of the application. For MVC (Model View Controller) architecture, the View Layer is always responsible for how the apps look and feels. React JS will let you compose complex UIs from small and isolated pieces of code termed as ‘components’. 

React JS has been created by Jordan Walke who is a software engineer at Facebook. Now, if you took the Instagram webpage as an example, you can understand very easily that how React JS works as it divides the UI into several components to make the code easier to debug. You can find the Search Component at the top, then Profile description, Stories Component, Single Post Component and Post List Component on the right. Each of those components has its own functionality and property.

What is React Native?

React Native will help you to create native apps which do not compromise the user experiences. It will provide a core set of platform doubter native components. With the help of React Native, one team can maintain two platforms and share a common technology known as React.

Advantages of using React:

The popularity of React JS is a notch above all other front-end development frameworks.  

Simplifies the overall process of the Scripting Components:

Scripting components will be much more comfortable while you use a free syntax extension called JSX. This syntax makes representation of an HTML quoting and subcomponent quoting as easier work. With the set of shortcut writings, it will make your code cleaner and simpler while writing ReactCreateelement. React JS is also helpful while thinking of the development of custom-made components or top-tier apps and makes it easy to convert HTML Mockups into ReactElement trees. Developers will also get error messages and alerts which are required. 

Create Dynamic Applications Easily: 

React makes it easier to create any dynamic web applications because it needs less coding and also provides more functionality as compared to JavaScript where coding may sometimes get complex very quickly.

React Native let you create native apps which will not compromise the user experience. It will provide a core set of platform components like Text, View and Image which can map directly to the platform’s native UI building blocks. 

Reusable components: 

A Single app can contain multiple components and you can say that components are the building blocks of React application. All the components have their own control and logic which can be reused on the application to decrease the development time of the apps.

React Offers more stable code:

React ensures a more stable code by using the downward data flow only so that the parent structure would not be affected by any little change which occurs in the child structure. So, to change any objects, a developer-only requires to modify its states, make amendments, after that only specific components will be updated. Such data binding structure will ensure code stability and make easy of the app performance.

Improved Performance: 

React using Virtual DOM which can create web applications faster. Virtual Dom will compare the previous states of the components and updates only those items in the Real DOM that were changed instead of updating all the components again as conventional web applications mainly do. 

Small Learning Curve: 

React is easy to learn as it is the combination of HTML and JavaScript concepts with some other additional features. So, getting trained and taking React Native and React JS certification will be an added advantage for the React developer as it is easy to learn also. However, you need to spend some time to get a proper understanding of Reacts library. 

Unidirectional Data Flow: 

React follows a unidirectional data flow so that while designing a React app, developers can nest child components within the parent components. As the data flow is in a single direction, it is easy to sort out any errors and got to know from where the problem arises within the application at the moment it occurs. 

Dedicated tools for easy debugging that are helpful for the developers

Facebook has already released a Chrome extension which can be used to debug React applications. This will make the debugging process of React Web applications easier and faster.

Learning new technology and using it in the next app project can be really great with the help of new technology that can be applied in the development field. That means a framework or library of React Js and React Native comes up with an entire toolset for smooth functionality and performance. 

Quick Rendering:

While developing a high volume application, the impact of the overall application performance is necessary. The Facebook Development team has thus introduced a virtual document object model which has been considering as one of the advantages of using the React framework for high-volume as well as dynamic app solutions. So, this will ultimately provide a better user experience, less consuming time and great application performance. 

React Js is SEO friendly: 

The ability to handle the common search engine problems (as it is not possible to read JavaScript high volume apps) can be easily sorted out by React JS framework. It can develop the software in an SEO friendly way.

Popular throughout the World: 

There are several well-known companies including Fortune 500 companies are using the React JS and React Native framework.  Some of the famous sites which are using React Js in their companies are Netflix, BBC, PayPal, IMDb, Coursera, Chrysler, Dropbox, Intuit, American Express, Reddit, NewYork Times, Lyft, Atlassian and lots more. 

So, for using React Js to develop any app is requires the company to hire of expert React developers and for this a proper training with React JS and React Native Certification course is required to prepare the candidate to crack a job interview in different companies.
