About ReactJS

ReactJS is an open-source front-end JavaScript library maintained by Meta. It is used for building user interfaces for single-page applications based on UI components. It requires only a minimal understanding of HTML and JavaScript.

Two main features JSX and Virtual DOMs, make React more than just a library.  

• JSX is syntax extension to JavaScript. It combines HTML syntax with JavaScript making it easier for developers to interact with the browser.
• Virtual DOM is a virtual copy of the DOM tree. Instead of manipulating the browser's DOM directly, React creates a virtual DOM in memory, where it does all the necessary manipulating, before making the changes in the browser DOM. React finds out what changes have been made, and changes only what needs to be changed.

Build Rich User Interfaces

A front-end application must have an attractive, responsive UI and a seamless UX with swift navigable views. An application filled with high-quality UI has more chances of getting noticed by the users. React allows building such high-quality, rich user interfaces through its declarative components, which brings us to our next point. This framework ensures the final product is well-design with super high quality to attract users to its key functionalities without fail. 

Reusability of components

ReactJS allows fragmenting large applications into several individual components. In React, a reusable component is a piece of UI that can be used in various parts of an application to build more than one UI instance. Re-usable components ensure that the user experience is consistent across all products. One more advantage is any component fault discovered in one product would be automatically repaired for all products. Because updating a component will automatically update all areas where the component is used, thereby enabling ease of maintenance.

Fast Rendering

Internally, React uses several clever techniques to minimize the number of costly DOM operations required to update the UI. For many applications, using React will lead to a fast user interface without doing much work to specifically optimize for performance. Updating DOM is a key factor when it comes to web performance. React is using something called virtual DOM to solve this problem. Any view changes are first reflected in the virtual DOM, then an efficient diff algorithm compares the previous and current states of the virtual DOM and calculates the best way to apply these changes. Finally, those updates are applied to the DOM to ensure minimum read/write time. It’s a much more efficient method that leads to faster rendering and leads to React’s high performance.

Strong Community Support

One of the main reasons to adopt React JS in your project is that React has very strong community support. It has very large community support on the StackOverflow forum to ask code-level questions or if you’re stuck with a specific error.

Better code stability

React JS ensures a more stable code by using downward data flow only so Any changes that occur in the child structure don’t get affected the parent structure. In changing an object, developers only need to modify its state and make amendments for specific components. This kind of data binding structure ensures code stability and smooth application performance. Additionally, it provides a fault-tolerant ‘UI’ because of the component creation aspect, which allows developers to efficiently conduct unit testing to avoid system crashes. Code reusability enables reducing time performing redundant tests to improve code quality giving stability to Code structure.

SEO-friendly

One of the relevant challenges that developers face is to ensure that an app is SEO-friendly. This is especially necessary for businesses in this day and age when there are several hundreds of apps out there. Normally the lower the page load time and the faster the rendering speed, the higher an app will rank on Google. React has fast rendering compared to other frameworks, it significantly reduces the page load time, which greatly helps higher rank on Google Search Engine Result Page.
