React JS Advantages: Why you should choose React for your app development

Share via:

React continues to hit the global developer charts for three years, remaining at the top of the most loved JS frameworks. Undoubtedly, the reasoning for this is steel-proof, and we are going to go into more detail about why React development is so popular, what React JS can do, and React JS benefits for mobile app development. 

What is React JS

React JS is a lightweight but powerful JavaScript library for building dynamic elements in web and app development. Just like any JS library, React is a set of pre-written code for everyday UI-related tasks. With the use of React JS developers can avoid the time-consuming process of manual coding. Often React JS is confused with a framework, but if anyone would be asking, “Is React JS a framework”, the answer is no. React JS is a library for mobile and web development. 

How does React JS work? Main React JS features are syntax JSX, Virtual DOM, XSS protection, Functional React JS components, and Basic state management with setState and Context API. A component is a combination of HTML and JavaScript code that includes the logic required to display a small part of a larger UI as a tree. Each of them can be built up into successively complex parts of an application.  

Why Use React JS

What is React JS used for? Before starting the React JS era in 2011, coders faced significant challenges in building UIs manually with the raw JavaScript or React’s predecessors like jQuery. The process was long, error-full, and cumbersome. So the processes needed automation and simplification. When Facebook engineer Jordan Walke created React JS, it significantly improved UI development. What is React JS good for?  It allows devs to create large web applications without overloading the page and works on user interfaces in the application.

React JS Benefits  

To explain why React JS is chosen by thousands of React JS development companies, let’s go over the top reasons they choose React.

It is simple

The first and the most apparent advantage of React JS over other JS libraries is its simplicity of use. It is easy to start if you have been using the JavaScript coding language and learned a few essential functions. 

It is reusable

React JS enables developers to create reusable components. Each UI element that you’ve already written can be used anywhere. React allows you to group these elements into sections or pages and insert them anywhere needed in the project with the same functions. Eventually, you get less code, less time and simpler testing, and more consistency.  

Easy iteration on components 

You can quickly update React JS components in a few seconds. The developer needs to define each component’s logic just once and maintain the changes of the selected items either in bulk or individually.  

Accelerated Speed due to Virtual DOM

ReactJS optimizes this by leveraging its Virtual DOM to speed up the websites. The virtual representation of DOM (Document Object Model) significantly cuts the time of the operation. React’s reconciliation algorithm calculates the minimal set of changes to be applied to the actual DOM. So instead of updating dozens of elements with every single change, ReactJS updates only one item that was modified. 

React JS App Development  

Saying that React was a revolution in mobile app development is not an exaggeration. 

React implementation is not limited to games, and not only Facebook is written with React JS.  Many complex single page applications, web and mobile, are done with this technology, too.

Developers build mobile iOS and Android apps without hiring additional talent. React Native is the React JS development environment allowing coders to create mobile applications in Javascript. They can reuse the existing code from the website instead of writing it from scratch. It significantly cuts development costs and time-to-market.

React vs. Angular

These two Javascript libraries are often compared: Angular JS vs. React JS. 

Developers often implement React in the React ecosystem with other libraries to turn it into a complete framework.

The Future of React

Almost one million pages are estimated to be React JS projects, and thousands of developers are actively implementing React for development. Such big market players as PayPal, Facebook, Instagram, Uber, WhatsApp, Airbnb, and many others are basing their web and mobile platforms on React JS.  

React JS has overcome many of the shortcomings, and today, no other library can beat it in developing dynamic, interactive user interfaces. Powered by a helpful developer toolset, quicker rendering, and the simplification of the component scripting process, React JS is here to stay in the development environment.
