0 Shares 0 Flares ×

React JS is one of the trending JavaScript libraries nowadays. Originally it was developed to build Facebook products, but as time went on it has gained popularity among developers at such companies as Yahoo!, Instagram, Sony and Airbnb. 


React JS is maintained and developed by Instagram and Facebook. Today it is supported also by a large community of developers. React development is suitable for any small, medium-sized, and large organizations. React capabilities such as easy scalability and application error tolerance allow quick creation of web projects of varying complexity. 


In the article, you will read about dedicated React JS programmers, the features and benefits of React JS, and how to get started Reacts JS development.

React JS Guide for Beginning Learning

Learning React requires some knowledge of JavaScript programming. The main advantage of the platform is that it is very simple and understandable for the user to study, besides it has a rather laconic structure of work. Working with the structuring of a web page is carried out through the DOM – this is a written program code of hypertext markup, which can be edited, deleted, placed, or manipulated whenever possible.


When a programmer starts the development, he does not need to use a boilerplate code generator – he just starts writing code. React lacks boilerplate code generators for components because they are unnecessary – they can be described as pure functions. Applying JSX syntax that renders like native and familiar HTML. This reduces the barrier to entry since a freelance React developer doesn’t need to learn fundamentally new things.

Amazing Facts to Know About React JavaScript Nowadays

React JS is a very popular library, especially among developers who want to build their own mobile apps. Since the mobile industry is rapidly developing, many companies have become interested in a professional React JS team that can effectively work with React JS to create applications and one-page sites.


Facts about React JS to know:


  1. React JS has many abilities

JS React allows breaking a page into simple modules. Then these modules can be reused in other parts of the website. Thus, a web application is made up of independent components, that also consist of smaller components, and so on. 


The development of a product reflects the benefits of modules splitting up. At the development stage, it helps developers take into account the architecture of the application, thus it will be more resistant to changing requirements. Another benefit is the ability to reduce product development time and delegate work between different developers.


  1. React JS works like a full-fledged framework


React JS robust ecosystem and extensibility make it a multifunctional JavaScript library. Because of this it can be mistaken for a complete framework. When a developer uses React JS to build user interfaces for websites and web applications, they gain access to React components and code snippets. It also has the ability to use JSX to manipulate the DOM directly.


  1. React JS website customizable

As soon as the user changes something in one place on the site, the changes will be immediately applied to all related data that is on the site (reactive paradigm). The most popular area of application: modern projects, business management systems, personal accounts, calculators.


Pages, links to which are in the visibility scope, are loaded with the background even before switching to them. All page templates are loaded immediately and pages are built from them on the JS side.

How Does a Website Work on React JS?

React.js sites work like this: when the page is loaded, an empty container (HTML) is loaded first, and then React renders the page content into it. If some part of the page changes, only the data for this part of the page is reloaded (not the whole page), and the update and rendering of the necessary parts of the page are carried out on the client-side. It speeds up loading and rendering and makes the sites very responsive.

Pros and Cons of Building React JS Apps

The introduction of new technologies is designed to simplify the life of developers and reduce development time for the customer. React is one of the fastest-growing technologies offering special benefits:


  • React JS is a library that easily integrates with other JavaScript frameworks
  • you can create high-performance websites
  • you can create a friendly search engine for web applications
  • division of the site into reusable modules simplifies its maintenance and reduces the impact of a single component on the entire application as a whole
  • projects developed in React JS can easily be ported to a mobile platform thanks to React Native
  • the functionality of the React JS is constantly expanding
  • the code is easy to read and write



  • third-party Javascript libraries are needed for full-fledged work, which complicates the development process
  • it is the lack of standards-based coding in HTML and CSS like Angular and Vue.js have.

What’s the Difference Between React JS and React Native?

React’s goal is to provide fast, simple, and responsive applications across multiple platforms. ReactJS is a JavaScript library that supports both front-end web and server-side for building user interfaces and web applications. 


React Native is a mobile framework that compiles with native app components, allowing you to build native mobile apps for different platforms (iOS, Android, and Windows Mobile) in JavaScript, allowing you to use ReactJS to create components, and implementing ReactJS.


React is growing in popularity rapidly, although it is relatively new. ReactJS is a great JavaScript framework released in 2013 by Instagram and Facebook. It makes it easy and simple to build complex and large-scale dynamic applications. This is about the top-notch rendering of high-performance user interfaces. 


With React, you can develop both client-side and server-side applications. The React platform is truly progressive considering how many companies have adopted it. React JS has been transformed from a simple troubleshooting idea into a solution that can greatly streamline web development efforts and improve efficiency.
