So let’s start with React and see, how it has become a game changer in the web development field. Before moving into depth, we will start with its basics. So be with us till the end.

What is React.js?

ReactJS is a flexible and open-source JS library, built and maintained by Facebook. It is used to build simple, scalable, and speedy user – interfaces for single pages as well as multiple pages. It allows the developers to build large web apps, which change the data without refreshing the page.

React JS has been developed and designed in such a way that it makes the frontend development fast and robust. It can be used with combinations of different other JS libraries and frameworks like Jquery, Backbone, and even with Angular JS.

Scalability is the major reason behind its popularity, and that’s the reason, why businesses are more preferring to Hire ReactJS developers, especially in the case of Outsourcing. So ultimately, it’s the best UI toolkit.

Do you know ?, There is an interesting story behind React js evolution? Let’s know it

History of React.js

In 2011, the Facebook ad has gained major momentum, it started facing various updates issues, which became difficult for its team members to handle. At that time, one software engineer called Jordan Walke came to the rescue, he created FaxJS, which was the first prototype, which made their process more efficient. Later on, this prototype evolved into the version of React js, that’s what we all know and love today.

In 2012, Facebook has started a company called Instagram, which was having only 13 employees at that time. It wanted to adopt some features of Facebook and created pressure on the parent company to decouple React.js and make it an open-source technology. In 2013, Jordan Walke finally introduced React js as an open-source technology. In 2014, React.js has introduced a new feature called “React Developer Tools” and it was added to the extension of chrome developer tools also introduced “React Hot Loader”, which was the plugin that allows the React components to be reloaded without loss of state.

In 2015, React js reached a milestone and gained much popularity with its features. Later, some big companies have begun using React, in their software development. Currently, companies like Netflix, Facebook, Instagram, Airbnb, and Dropbox are using React js in their web development.

Why ReactJS?

Now the question is, why should we use React.js in front-end development ? as there are so many open-source technologies around. React js is mainly responsible for handling the view layer of mobile and web apps. It allows developers to create web applications, which can change the data without reloading the pages.

So let’s have a look at its awesome features, and find out why it’s best for developing the front end?

Features of React

These features will help us to understand how React js works.

Virtual DOM

Virtual DOM is the representation of original DOM components, it works like a one-way data-binding structure. Whenever any modification is done in the web application, the virtual DOM renders the entire UI again. Then it checks the difference between the previous DOM representation and the new DOM. After this, it updates only those components, which have been actually modified. This saves time as well as development costs.


JSX stands for Javascript XML, it’s a syntax extension of Javascript. It describes the appearance of the interface of an app and makes the syntax just like HTML and it is processed into Javascript calls of React Framework. It helps the developers to create React components.

This feature of Reactjs is extremely easy for developers to write building blocks.

Declarative UI

This feature makes the code easier and more readable to fix the bugs. It is the best platform to develop exciting UI for both mobile apps as well as web apps.

Unidirectional Data Flow or Flux

In Reactjs data flows in one-way only, which makes the clean data-flow architecture. The most benefit of this architecture is, that your data flows in a single direction throughout the app giving you better control over it. Flux is a pattern, that keeps your data flow Unidirectional. This one-way flow pattern makes the application more flexible and increases efficiency.

Reusable Components

React is a component-based architecture. Its applications are consists of multiple components. Each component has its own control and logic. The best part is these components are reusable, which helps you to reuse the components whenever needed and maintain the code on large-scale applications.


React js and JSX makes the application simple as well as easy to code and understand. The components-based approach, allows the developers to reuse the components. This makes the applications simpler and clear. Being simple is one of the major benefits of React js.


React allows you to write reusable, smaller codes instead of writing large codes. The modularity of React js is the best solution for JS visibility issues.


React js provides various supports for application architecture. It supports server-side rendering, Redux, and Flux in web app development. React is one of the most popular frameworks for cross-compatible mobile apps


As React has large community support. Testing is easy for React-based applications. Facebook provides a smaller browser extension, which makes debugging easier.

Advantages and Disadvantages of React.js

It seems React is present everywhere. Today, the majority of websites on the web are using React js. Therefore, it has plenty of advantages. So, Let’s see some of the major benefits of using React js for web applications.

Ease of Learning

Easy learning is one of the core advantages of React js. That’s the reason, more and more companies are leaning towards React. The libraries are easy to learn and implement, so businesses can have a quick start with them. It includes features like dependency injections, which reduce the learning time for beginners.

Speedy App Development

React makes development easier, because of reusable components. It allows the developers to integrate different functionalities easily, without the need to code from scratch. This reduces the overall development time and increases the quality as well.

One-Way Data Flow

Usually, the framework processes two-way data binding, which means one change in the web application can affect the entire application. But Thanks to the one-way data flow structure of React, which only changes the required places without disturbing parent components. Due to this, developers can have control throughout the applications which makes them stable.

Virtual DOM Components

React js Virtual DOM is responsible for both performance and speed. Using this DOM, developers can create applications much faster than usual. It’s a tree structure of XML, HTML or XHTML. It allows the developers to update even the smallest components without influencing others. That’s why it requires less time to update than the actual DOM.

Long-time Application Stability

Any business owners or especially start-ups want their applications to be stable for a long time and not go down with time. They want their applications, should be enough powerful to adopt the new features with time. Therefore, React is the best choice, as it is backed up by Facebook and many other large communities, and assures you of long-time stability for React applications.

Performance Enhancements

Virtual DOM improves the performance of React js. Most of the developers have faced slow performance problems while updating with DOM. But React js has solved the issue by introducing virtual DOM. This Virtual DOM provides a faster and smoother experience.

SEO – Friendly

SEO i.e “Search Engine Optimizations” is able to increase huge traffic to your site, if done in the correct way. It is able to rank your sites on various search engines. Traditional Javascript has an issue while dealing with SEO. But React js has overcome all the SEO issues and helps the developers to be easily navigated on various search engines. Because React applications could be able to run on various servers, virtual DOM will be rendering and returning to the web browser as a single web page.

Although, there are plenty of benefits of using React js, that owners love to have. But there are also some disadvantages, that owners should keep in mind before using React js for web development.

Can be Expensive

Sometimes, it could be expensive, to hire react js developers. React developers typically charge $80-$100 per hour depending on the locations and other factors. So it is quite expensive compared to other frameworks.

JSX as a Barrier

Though JSX is a Javascript extension, which makes the code more readable and clean. But sometimes it becomes complicated for the developers to handle. Therefore in spite of having benefits, it works as a barrier too.

Remaining Up-to-Date can be difficult

React js is an actively large community and changes frequently. It can also serve as an advantage but sometimes it becomes difficult for the developers to constantly stay updated with the latest technologies.

Lack of Documentation

It is one of the major drawbacks of React js, as we have mentioned, that the technology constantly updates. So there is not enough time to make proper documentation with the constant changes. To overcome this, developers note down these changes on their own.

Focusses only on View Part

React js focuses only on the UI layers of the application, that’s why you still need to choose some other technologies to get complete tooling set for web development.

React Server-Side Rendering will enhance App-load Time

The major benefit of React is its server-side rendering, and it is likely to get more acceptance in the coming years. It is mainly due to two reasons

  • React’s page components are rendered on the server and sent to the browser with server-side rendering which speeds up the page render time.
  • Further, the load time can be reduced by “ReactDOMServer”, which serves HTML markup directly from Node js to the client.

The React team is planning to improve these areas with the best server-side rendering techniques.

More developers are likely to choose React js

As per the latest report, more developers have turned towards React js and this number will increase in the upcoming times too. According to State Javascript Survey, the usage of React has increased from 72 to 80%. So, it is clear this trend will remain in the coming days too.

React js will be the first choice for Startups and Entrepreneurs

Every business tries to find out a cost-effective way to grow. That’s why they find a digital way, which can meet their business demands at a minimum cost. So to do this, one needs to choose the technology that is cheap.

React js has proved to be a cost-effective technology while developing a web application. It optimizes the coding and makes it easier for the developers to complete the project within the time frame. This means, more startups and entrepreneurs will move towards React js.

Better Scope For Development

Comparison of React js vs Other Frameworks

While React js is the best framework, that’s why every developer wants to use it on regular basis, other frameworks are also effective. So let’s look at the comparison of React js with other frameworks.

React vs Vue js

The choice between Reactjs and Vue.js is debatable. Vue js has an ever-growing community and on the other hand, React is also continuously updating its technology and adding new components. Therefore, React is also not leading behind the popularity.

If we talk about React vs Vue, both are tremendous when it comes to speed. In React js, when any changes occur, re-rendering is triggered for the entire components and changes only those components which need to be updated which in turn increases the speed. While in Vue js Components are tracked automatically during rendering, which means the system knows the components which required re-rendering.

React vs Angular js

Reactjs vs Angular.js is also a popular ongoing debate now. React is a JS library whereas Angular is a frontend framework. React uses one-way data binding and virtual DOM while Angular uses two-way data binding and real DOM. So from these React is considered a faster framework than Angular. Additionally, React developers can get a myriad of solutions for any problems.
