Why Use React JS? Best Use Cases for React.js

Every year, new libraries are launched because of the rapid pace at which the digital world is evolving. It’s understandable that choosing which library or framework to utilize for which project can be challenging.

React is a JavaScript toolkit that divides user interfaces into composable components and produces user interfaces for single-page apps. It was originally developed for Facebook.

But the question is still intact- Why use Reactjs?

React has grown in popularity as a front-end web development tool since it only requires a basic familiarity with HTML and JavaScript. This post will go through the projects your firm needs to employ React.

React.js – An Introduction

ReactJS is a JavaScript component library for building website and application user interfaces. Jordan Walke created it in 2011, and it sets a new standard for designing quick and dynamic websites with JavaScript.

Here’s another query that arises- What is Reactjs is good for?

React provides coders with resources for creating reusable and readily integrable UI components that minimize development time and create a responsive user experience for websites, web apps, and mobile apps.

Website elements like buttons, links, menu tabs, or search bars that help users interact with the website are the User Interface or UI. Front-end developers can leverage React’s extensive UI components to create personalized interactive pieces.

React helps create an application’s View Layer (including all page portions visible to users).

What’s So Special about React.js?

For example, while creating a dynamic front-end or SPA, you’ll require client-side routing to ensure that the end-user has a quick navigational experience. Now, when you use SSR, you don’t want to lose your navigation.

You can still utilize Reactjs on the client-side to implement navigation. This means that the initial render is SSR-based, while future navigations are SPA-based. You’re also not going away from SSR with React; you’re only using it when it’s needed.

Further wasting time, let’s talk about why we should use react js?

Benefits of Using React.js

Here are the reasons to choose React for your next project.

1. Smooth Learning Curve

React is a lightweight and straightforward library that only works with a web page’s view layer. It has a simple learning curve, making it easier to get started than its JavaScript sibling, Angular.

You can quickly get started with React if you have a functional understanding of HTML-CSS and a rudimentary comprehension of programming ideas. However, if you’re coming from another framework or library, adjusting to React’s unique ways may take some time.

Apart from that, React has no concepts or features that are difficult to grasp. However, there is a wealth of documentation accessible online to assist you with everything ReactJS-related.

2. Build Rich User Interfaces

If you have been looking for the answer to your question – What is react.js good for? Your search ends here!

In today’s world, the quality of an application’s user interface is critical. If the user interface is poorly designed, an application’s chances of success are reduced.

However, if an app has a high-quality user interface, there’s a higher probability that your users will enjoy using it.

As a result, creating rich user interfaces is almost necessary for an app to survive and prosper.

The good news is that React’s declarative components enable us to create such high-quality, rich user interfaces, which leads us to our next point.

3. Creates a One-of-a-kind Abstraction Layer

Another lesser-known business benefit of React is that it provides a good abstraction layer, preventing end-users from accessing the complex internals. Your developer simply needs to grasp the fundamentals, and it’s best to understand the internal workings. Furthermore, architectural patterns like MVC, MVP and MVVM are not mandated. Your app’s architecture can be designed in whatever way your developer deems fit.

4. A Sizable Community

This is one of the major reasons you are still considering why we should use React.js?

Jordan Walke’s open-source library, React.js, is one of the top five trending repositories on GitHub. It has a sizable community of JavaScript developers who constantly create new solutions and tools. The official library now includes a large number of user-developed programs.

To address any problems, you can tap into a vast community of professionals. Furthermore, this is a fantastic method to stay informed. React now has over 165K ratings on Github and around 10 million npm downloads.

5. Virtual DOMS

The Document Object Model (DOM) is a tree-based interface representing HTML and XML code. A web browser creates a DOM-like model to generate output, considering each object/element of HTML code as a node in the DOM tree.

The DOM tree has to be rendered every time the HTML code changes, whether due to user input or value adjustments, which takes a long time and consumes a lot of power. The use of Virtual DOMs saves the day here.

React copies the DOM and keeps it in memory as a cache. It evaluates the Virtual DOM every time a change is performed and determines which tree nodes and components need to be updated.

You can update the tree quickly and efficiently with just a small change in the DOM. This saves a lot of time for developers and makes the software incredibly speedy and responsive.

6. Reusable Components

You begin with minor components such as buttons, checkboxes, and dropdown menus and then build wrapper components out of those smaller components. Then you write wrapper components at a higher level. It continues in this manner until you have only one root component, which is your program.

Each component is responsible for determining how it should be presented, and it has its logic within it. This method yields some incredible outcomes as you can use the components in any situation. As a result, (1) your app has a consistent appearance and feel, (2) code re-use makes your codebase easier to maintain and scale, and (3) your app is easier to create.

Top Uses Cases for React.js

Here are the top react use cases that you must know:

1. Facebook, Instagram, and Netflix

As mentioned previously, react.js was designed by Facebook and Instagram developers to construct interactive components within a user interface. The react library was released as open-source in 2013 and has since grown in popularity. While Facebook and Instagram continue to employ React, other well-known products, such as Netflix, have begun to do it as well.

2. Khan Academy

In the mid-2000s, Khan Academy became famous as an instructional lesson that students thought was particularly good at presenting fundamental topics. Since his first YouTube videos, Khan has established his website to host, classify, and add more features to his work. This website has a lot of React samples.

3. Airbnb

In the hospitality industry, Airbnb was genuinely groundbreaking. It was the first time that homeowners had access to a network that enabled them to rent out rooms in their homes, holiday homes, or condominiums. Anyone who has used the app or website can attest to their engagement. They used the React JS package to create nearly all of the components.

4. WhatsApp

WhatsApp is an excellent example of React JS use cases and how widely the React JS library has been adopted. Previously, many of the components would have required the integration of HTML, CSS, JavaScript, and innovative server-side functionality. React JS eliminates the need for so many different components and replaces them with a single, streamlined approach to construct them.

5. Discord

Discord began as a chat service for people who shared an interest in playing online video games. The platform has since evolved into an online hangout for people with common interests. Anyone may establish, moderate, and personalize a Server to invite others to talk, share photos and videos, and trade data. The Discord UI features are all very interactive, and they’re all built with the React JS toolkit.

6. Yahoo Mail

Since Facebook owns Yahoo mail, this should not surprise most people. Yahoo mail requires a lot of regular updates. They used a Model View Controller pattern for several components, better suited to smaller projects. Implementing React allowed for more modulation and made upgrading the user interface easier,” explains web developer Ben Sheen.

7. Vivaldi Web Browser

The Vivaldi Browser has become increasingly popular in recent years, and for a good reason. They used the React.js package to create its highly reactive user interfaces.


React is a well-known JavaScript package that is utilized worldwide, as detailed in this blog. It comes with cutting-edge features and is ideal for developers searching for a simple to use and highly productive JavaScript framework.

New libraries and web frameworks are produced every year, making it difficult to forecast which technology will be there for the long haul. ReactJS, on the other hand, has outlasted Angular, Django, Vue, and Ruby on Rails over the last ten years.
