7 Key Reasons why should use React JS for Web Development

The JavaScript library known as React was created by Facebook and is one of the technologies that went into the Web Development Services of the Instagram website. Its purpose is to facilitate the creation of user interfaces for websites and software applications that are both quick and easy to use. The virtual DOM is the fundamental idea behind React.js. It is a tree that simulates a DOM tree and is built using JavaScript components and the React framework. In order to maintain the most recent version of your React components, it does the smallest amount of DOM alteration that is technically possible. However, there are several other reasons why Reactjs development is best for Web development course. The seven most important reasons that you must know are mentioned in this article. 

What exactly is this React JS?

In its most basic form, React JS is a JavaScript library that was developed and is managed by Facebook. React was developed by Jordan Walke, who is also the author of React JS. According to Walke, React is an open-source JavaScript toolkit that is efficient, declarative, and adaptable. It is used for developing web application front ends that are simple, quick, and scalable. Since its inception, it has dominated the front-end development space.

Key Reasons why React Js is best for Web Development

1. Quick Learning Curve

A relatively straightforward and lightweight framework, React Js is focused solely on the display layer of the application. It is not a monster like Angular or Ember, which are both examples of other MV* frameworks. After devoting just a few days to reading the instruction, every Javascript developer is capable of grasping the fundamentals and getting started on the creation of a fantastic online application. Besides, there are a lot of reactjs experts available online who can teach you

2. Reusable Components

A structure that is based on components is provided by React Js. Components are like your lego components. You begin by creating smaller components like buttons, checkboxes, dropdowns, and so on. After that, you develop wrapper components that are made up of those smaller components. After that, you will develop wrapper components for higher levels. And this continues until you have this one root component, which is your app; it continues until you have this root component. 

Every component is responsible for determining how it should be presented. Each component contains its own unique logic on the inside. This strategy yields some very incredible outcomes.

3. It aids in the creation of complex user interfaces.

The quality of the user interface of an application is becoming an increasingly significant factor in today’s world. When a program’s user interface is badly designed, it decreases the likelihood that the application will be successful.

However, if a program’s user interface (UI) is of a high quality, then there is a greater likelihood that consumers will like using the application.

For this reason, developing applications with rich user interfaces is almost essential for their continued existence and success.

The good news is that ReactJs  makes it possible to develop such high-quality and rich user interfaces by utilising its declarative components, which takes us to the next issue in our discussion.

4. Quicker Updates 

When an app’s logic is complicated and a single change in one component might have a significant impact on other components, frequent updates can quickly become a source of stress for the developer.

However, in order to address this issue, Facebook has improved ReactJs by adding a functionality that allows components to be reused. The reusability of components is one of the key features of React, which essentially enables react js developers to reload the same digital objects.

The method is also very easy to follow! – For instance, developers may begin by adding simple components like buttons, text fields, and checkboxes, and then they can move those components to wrapper elements, which are then finally carried forward to the root component.

This strategy, in its most fundamental form, results in improved code maintenance and growth. This is because each component in React possesses its own internal logic, which is simple to alter and, as a consequence, increases the efficiency with which applications are developed.

5. Virtual DOM

React’s lightning-fast rendering speeds are made possible by the fact that the DOM is kept in memory and virtualized, so any changes made to the view are instantly reflected in the virtual DOM. The virtual DOM’s previous and current states are compared using the diff method, which then determines the least disruptive approach to implement the modifications. The total performance is then improved by introducing the fewest possible updates to obtain the quickest read/write time.

When DOM is virtualized, the frequent updates that slow down systems are minimised and optimised in a smart way. All the changes to the virtual DOM occur “behind the scenes,” i.e., internally and autonomously, which greatly reduces the amount of hardware resources required. 

6. SEO-Friendly

SEO is the backbone of every thriving online company. When compared to competing frameworks, React Js drastically reduces page load times, which is very helpful for organisations aiming for the top spot in Google’s SERP. In addition, React JS is in a constant state of evolution. It has a sizable community. 

7. You get to learn React Native

You get an extra feature when you learn React js: React Native. Contrary to what its developers claim, React is more accurately described as a “learn once write anywhere library.” Assuming you have an Android or iOS device, you can use React Native to create native apps for those platforms. While you won’t be able to copy-and-paste your web code directly, you may reuse the same approach and structure.


Component reuse, virtual DOM, unidirectional data flow, minimal weight, and reliability are just a few of React’s many benefits. There is merit in knowing the library due to its usefulness and widespread use. Now, at long last, this blog has come to an end. Hopefully, after reading this, you can see why React JS is such a great front-end framework.
