What is React Js Development and Why is it so popular?

ReactJS is an open source JavaScript library designed by Facebook for creating well structured, scalable and reusable web apps fast. The core objective of ReactJS is providing the best possible rendering performance. It also provides a facility to create reusable UI components. The strength of ReactJS comes from the focus on individual components instead of working on the entire web app.

Importance of React Js:

• ReactJS is a popular JavaScript library that has been around since the Facebook days. It is known for providing the solution that developers were looking for. It allows developers to create simple components and complex animations, as well as help in developing web applications.
• It uses JSX (a unique syntax that allows HTML quotes as well as HTML tag syntax application for rendering specific subcomponents) which is very helpful in promoting the construction of machine-readable codes and at the same time compounding components into a single-time verifiable file.
• React JS is a JavaScript library that lets you create high-performance, innovative user interfaces using reusable components. React JS is officially maintained by Facebook and Instagram, but it has a vibrant developer community that contributes to the codebase.
• ReactJS Development is one of the most trending front end frameworks these days. Many developers have been using this library to build user interfaces. ReactJs allows developers to create large Scale web applications that can change data, without reloading the page. The major objective of React is to be fast, scalable and simple. It can be used with a combination of JavaScript libraries or frameworks, such as Angular JS in MVC.
• ReactJs Framework is a declarative, efficient, and flexible open-source JavaScript library for building simple, scalable, and fast frontends of web applications. React brings innovations to the world of JavaScript by creating a virtual DOM that can render your application faster than the browser while remaining small enough to encourage reuse.

Reasons to Choose ReactJs for Your Business:

Easy to Learn and Use Reactjs- ReactJS is one of the most sought-after web development skills. The main advantage of this technology for hiring managers is that you can find React developers easily. React is not only easy to learn but also very easy to use. A developer who already knows JavaScript should have no problem learning ReactJS. Not only is it easy to learn, but also easy to use and maintain, making it one of the best web development languages out there today.React is a JavaScript library for building user interfaces. It's used by companies like Facebook, Instagram, and Netflix. It designs simple views for each state in your application, and ReactJs will efficiently update and render just the right components when your data changes.

It’s Easier to Write with JSX- Developers using JSX will be glad to know that this Javascript extension is compatible with the React library. They have HTML quoting and make subcomponent rendering easier. It’s essentially a group of React-writing shortcuts with a few rules that make your source more readable and straightforward. JSX is a JavaScript-like language that provides developers with the capability to compose a tree of ReactElements directly in their HTML documents, easily making the transition from HTML mockups to ReactElement trees. JSX is controversial, but it can be useful in designing high-volume apps or bespoke components. It also prevents errors by providing warnings and error signals to React developers, and helps prevent code injections.

Seamless SEO Integration- React js, which has gained popularity in recent years, is an open-source JavaScript library provided by Facebook. Though it was initially developed for the purpose of powering web pages on Facebook's website, React is now used in many different web applications. This relates to a search engine site as it can be used as a solution. As a result, users are able to leverage Reactjs as a helpful developer toolset.React JS is not the only front-end JavaScript framework but it is certainly the most widely used one in 2018. Many large firms like Facebook, Slack and Twitter rely on React JS to design applications today. It has been around for several years now and its popularity has grown exponentially thanks to development teams that value usability, performance, and cross-platform compatibility.

Diversified Developer Toolset Like Virtual DOM- React is a development framework that originates from Facebook and Instagram. It helps in building interactive user interfaces. The toolkit is capable of rendering HTML elements based on the data provided. In Web Development ReactJs framework is capable of offering vivacious and diversified tool sets. Development tools in React are exciting, but only if you can put them to work in a development setting. It implies that these tools are capable of assisting you in designing and debugging the new technology. Hence, there are numerous design and debugging tools in React.Virtual DOM is an important aspect of interactive web development. Elements of this app are grouped in DOM trees, which allow scripts to access the many aspects of a webpage. If a DOM manipulation takes place, the complete elements have to be re-rendered. ReactJS uses a virtual DOM to save memory and time by only re-rendering those components that were modified.

Strong Community Support- React is an open-source web application development platform which was very popular in the last year. Virtual representation is good and says something and the internal logic is different and this leads to inappropriate or lack of code stability. They have new tool’s to be another concern that doesn’t work well for mobile app development but may work for web apps. The development community provides consistent support for all types of challenges related to scripting components, development environment or any other type of component structure issue. ReactJS provides an efficient way to create reusable UI components that make your overall app development more productive and simpler. Framework offers similar patterns for both mobile and web development, which is one of the main advantages of using it.

Features of React Js-

• React.js is declarative
• React.js is Simple
• React Js is component based and extensive framework
• React Js supports server side rendering
• React Js is fast and easy to learn

JSX- React uses a markup language called JSX to bind the user interface. This allows you to write the components in a more human-readable format and compile them into regular JavaScript code.

React Native- The React Native framework combines the power and familiar design of React, with the flexibility of native device components. It’s engineered by Facebook and Instagram to be made of pure Javascript and it uses the same fundamental UI building blocks as regular iOS and Android apps. The best part of the React Native framework is that it allows/admit components written in Objective-C, Java or Swift.

Single-Way data flow- It is known that React uses a virtual DOM to manipulate the data and display them in a different manner. The interaction between user and our application is handled by using observables that are handled both at nature level as well as the state level. Code bases are written in jsx which allows us to write JavaScript code and after compiling it converts into normal JavaScript (JS) code.

Virtual Document Object Model- A React component receives its properties as HTML attributes. It cannot directly modify the properties passed to it, but can pass call back functions through props in its HTML tags. Upon receiving this call back function, we can do modifications on that particular property which is passed as an attribute. This complete process is known as "properties flow down; actions flow up".

Advantages of ReactJs:

Speed- React allows developers to utilize individual parts of their application on both client-side and server-side in order to optimize the development process while maintaining a seamless experience for the users, including the most popular social media website Facebook.

Flexibility- ReactJs Development has been a staple in frontend frameworks for quite some time. Compared to other frontend frameworks, the React code is easier to maintain and is flexible due to its modular structure.

Performance- React JS was built by Facebook to provide a view layer for web applications. The core of the library offers a virtual DOM and server-side rendering, which allows complex applications to run at a high frame rate.

Intuitive- ReactJS is a UI library which is extremely intuitive to work with. It enables fast and quality assured application development that, in turn, saves time for both - clients and developers. The app developed using ReactJS technology is interactive and provides great user experience.

Declarative- ReactJS is a JavaScript library developed and maintained by Facebook to create UI components. It allows data changes that trigger automatic alterations in the selected parts of user interfaces. Not only does this device have a good interface that is well suited for different users, it also has a progressive functionality. This means that there is no additional function that you need to perform in order to update the user interface.

Provides Reusable Components- ReactJS is a JavaScript library that helps in building scalable and reusable web applications. It lets the developers reuse components by creating a new application and thereby reducing their development efforts. ReactJS is lightweight and it ensures optimum performance for all the applications.

JavaScript library- The JS library consists of several functions including one that converts the HTML components into required functions and transforms the entire project so that it is easy to understand. A strong blend of JavaScript and HTML syntax is always used, which automatically simplifies the entire process of writing code for the planned project.

Components Support- ReactJS is a JavaScript framework which helps to deal with the interactions between components. It is known as a reactive programming library which clearly represents the model-view-controller paradigm and assists to solve multi-level problems in an efficient way. The JS codes are used for creating reusable UI components that work with virtual DOM written in JSX format.

SEO-friendly- ReactJS is the first library to enable developers to create SEO-friendly, energy-efficient UX on the web. With React's virtual DOM and innovative, reactive programming paradigm, developers get the best performance by building apps that scale seamlessly.

Proficient Data Binding- A one-way data flow in ReactJS. It is very easy to use and it is simple. This flow has two-way data binding which is a rare feature for an open source library or language.
