What Are the Benefits of Using React.js for Web Development

We all must be knowing that React.js is a JavaScript library, but in this article, we are going to discuss that what are the differences and unique features present in React.js that makes it different from any other JavaScript Framework.

Before heading towards the main topic, here’s an interesting fact about React.js is that it’s not a JavaScript framework, instead of that React.js is a JavaScript library. Yes, but we can say that it has some elements of a framework also present, because of which it is sometimes notified as a JavaScript framework.

What is React.jS?

As mentioned above that React.js is an open-source JavaScript library, and the primary usage of it is to create user interfaces that generally helps to create single-page applications.

Who created React.js

A software engineer Jordan Walke created react; interestingly, he was one of the software engineers that was working for Facebook. He released an early prototype of React called “FaxJS”.

No JavaScript library helps to create reusable UI components, but in the case of React, we can easily do so. This was the purpose of building the React.js library.

If you are interested in following Jordan, take a look at his Twitter profile.

Why React.js

In the starting, we have asked a question from you that why React.js is the best and mostly used? So the reason that makes React to be the most used JavaScript library/framework is that it’s fast, easily scalable, and straightforward. These factors you would be able to notice when you create an extensive web application with the help of React. Because with the help of React, you can easily create large web applications that can change their data without even reloading the page, so just the changeable data gets altered and nothing else.

Moreover, with React, you would be able to use other JavaScript libraries and frameworks too. Some of them are Angular JS and many more.

Who is using React.js

Several older companies and even new startups are using React JS because of the features offered to its users by the React team. Facebook and Instagram are the top companies in this list. Other giants using React as their technology to build and maintain their web applications are listed below.

Features of React.js

Several questions were pointing out regarding the naming of React JS, so let me tell you that it has a total of three names those are React JS, React, and React.js.

Let us now have a thorough look at the features of React JS.

1. JSX support

When you are using react, although you can use the regular old JavaScript in it, but it is more preferable to use JSX. Now JSX is a JavaScript in which you can use both XML/HTML and JavaScript/React Code. The primary usage of JSX is to create react elements, and the reason JSX is highly used is as follows-

Firstly if you develop using JSX, the overall quality would be unmatchable with JavaScript development.

The second important reason for using JSX is that that optimization is faster, and Code compiles faster than ever. While in the case of regular JavaScript, you would not be able to take any such advantage.

2. The power of Redux

Components follow the tree structure and hence the states needed for each component need to be passed as the props. This is not a big issue in the case of a basic react application. But when things go high, passing states as props will not be a good option. Redux is the solution to this problem.

Redux is a state container for JavaScript apps that works perfectly with React. Don’t confuse with WordPress’s Redux framework and Redux. Redux is a simple JavaScript library that helps to manage states in any JavaScript-based apps.

Note: It doesn’t need to use a Redux inside a React app with fewer components and states. This makes our project more complicated.

3. React Native

React Native is the libraries that other application platforms can use for getting react architecture. Some of those platforms are iOS and Android.

With the help of react-native, you can only build mobile apps, and it uses only JavaScript. Moreover, you would be able to take advantage of mobile UI library components that come with React. In short, we can say that with the help of React native, you can create mobile applications for any platform. The plus point of it is that you can also use various components that are written in Java, Swift, or Objective-C.

Some interesting facts about React Native

  1. React native is built by Facebook, and it an open-source library.
  2. Several companies have started using React Native for their app development.
  3. You can even integrate react native in any already built android or iOS application.
  4. Single-way data flow- In the web development field, you must have noticed how difficult it is to retrieve back or make changes in the components created. But when you are using or developing with React, you would be able to make modifications easily as you would be offered a call back function. This whole process of using the call back function is called Properties flow down: actions flow up.
  5. This single way of data flow is specially created by taking care of the problem of making changes in web development.
  6. Virtual Document Object Model- Here, we are going to have a look at another problem that several web developers face. That is when they make changes in a single component of the web application. At that time, they have had to make changes on the whole page, and in this case, they have had to do more work.
  7. While, when you are using React JS, you will notice that with the help of an in-memory data structure cache. Only the place where changes are done gets only changes, and nothing else would be affected. With this feature, the react library only renders those components, which are changed.
  8. Do you know that right now, React is working on making a change into their React’s core, which is the addition of React fiber. As whenever there was animation or any other such gesture in the web application, the VDOM was unable to make it highly suitable. But with the help of React Fiber. They would be able to enhance the suitability in places such as animations, gestures, and many more.

Why is React.js the best?

We have reached the main question because of which we have started this article, and that is why React JS? Why is it so different, so good, so unique, and many more why’s. Do follow this article till the end to know every single feature that makes React JS different from every other JavaScript Frameworks.

1. Simple

If you have ever used React JS, then you must have noticed that working with React JS is so simple. Moreover, no matter you are new to developing or not, you would be able to fetch everything about this JavaScript library easily. While several people think that for creating a professional web application, we would need to gain to high knowledge about React JS. But the truth is that if you have even the basic knowledge about it, then also you would be able to create any type of professional web application quickly.

2. Easy to learn

It is said that those who are already linked with programming can easily learn React JS, which is true but I think that React JS is so simple, exciting and easy to learn that those who are not linked to programming before they would be able to learn it easily. In case you are new to React JS, let me tell you that you need to have knowledge of CSS and HTML for getting started with it.

3. JSX support

Moreover, as we discussed above that React uses JSX, which is an advanced and easy form of JavaScript, which makes it highly efficient and productive. Although developers can also use the regular JavaScript, but with the help of JSX, you would be able to use the combination of XML/HTML and React Code. JSX also helps in creating several React components.

4. React Native Approach

Here’s another feature that makes React JS so unique and different from every other JavaScript Framework, and that is its native approach. As we discussed above that React Native is a feature with the help of which you can create mobile applications from various platforms such as IOS and Android. Moreover, with the help of React Native, you would be able to use components, which are created with JavaScript, Swift, or Objective-C. You can even integrate React JS in already built IOS and Android applications with the help of React Native.

5. Data Binding

Firstly, React JS uses a one-way data-binding feature, and under this type of data binding you, everything works in a series. Moreover, the plus point of one-way data binding used by React JS is that you would be able to control the overall flow of all components present with the help of the dispatcher. We can say that it’s a control point.

Let us have a look at some of the benefits of using one-way data binding feature-

The first and most crucial benefit of one-way data binding offered by React JS is that it would be easier to debug the various components of React JS web applications.

The second crucial benefit of one-way data binding is that you would be able to track down changes easily.

The last benefit in the list is that the overall process of problem tracing in a one-way data-binding system is way lot more comfortable and faster.

6. Testability

Here’s one more reason to fall in love with React JS, and that is it’s super easy testing ability. In React, you can directly treat react views as functions and hence would be able to have a look at outputs, actions, events, and many more things related to testing.

What Are the Benefits of Using React.js for Web Development

Let us have a look at the top 10 benefits of React JS because of which it is listed as the best for web application development-

1. Support for JSX syntax extension

The first benefit of the list is that you are offered JSX and JavaScript for writing components. Although you can use JavaScript efficiently JSX is easier to work with as it provides the combination of XML/HTML and React.js Code. Hence, it is also beneficial for the creation of React Components.

2. Virtual DOM support

You must have noticed that whenever the developers have to make some changes in a single component of an already-built web application. At that time, they had had to face several problems. From which some of them are compilation errors, some components fail because of change in another element, or many more such issues.

But in the case of React JS with the help of VDOM, you will never face any such problem as whenever you make some changes in the web application. Firstly, you would be shown a review from VDOM, and if everything goes fine, then you can apply those changes.

With the help of VDOM, you would be able to get the fastest rendering for your web application. The primary reason behind VDOM’s fast working is that it works in layers. When changes are made, the changes are even applied in layers.

Note:- Fiber is the new reconciliation engine in React 16. Its main goal is to enable incremental rendering of the virtual DOM.

Let us have a look at some benefits of VDOM-

The first benefit of VDOM is that whenever there’s a change in the web application, the whole UI will be rendered in the VDOM representation.

With the help of VDOM, you would be shown the actual changes that you would be able to see with the changes made in the components.

After you have seen the changes and everything is correct, you can apply those changes, and hence, the real DOM would be updated.

3. Stability in code

With React JS, you get the most stability in your Code; this is because when even a small change is made at that time. The change is only made on that particular component, while the parent structure is not disturbed. This is the reason coding on React JS is the most stable.

4. SEO friendly

Another benefit of using React JS is that it automatically deals with common search engine optimization failures. Hence, we can say that it’s SEO friendly.

5. It Offers a Helpful Developer Toolset

The sixth benefit in the list is that with React JS, you are offered a helpful developer toolset. With the help of this toolset, you would be able to make your development journey with React JS more enjoyable and easier. Moreover, these developer tools can be used for both Chrome and Firefox as it’s available in the form of a browser extension.

6. Easier Conversion from a React.js Web App to a Mobile App

React JS also offers React Native with the help of which you can even develop Android and IOS applications. Moreover, in the development of these applications, JavaScript would be used.

7. Easy to Learn

You can quickly learn React JS. If you are getting started with it, then fetch some knowledge about CSS and HTML before moving to React JS.

8. Community Support

React Library is being supported by Facebook and Instagram, which states that an active community is backing it. Moreover, with the help of which they are making several changes in the React library daily for a better experience.

Pros and Cons of React.js

In this world, nothing is perfect. Everything has its advantaged and disadvantages. Let us have a look at the Pros and Cons of React.js.


  1. The first Pros of React JS is that with the help of VDOM, the overall experience of development is better and faster.
  2. We can even reuse React components with the help of which we can save our time.
  3. The one-way data flow helps us offer a stable code.


  1. The React.js’s environment keeps on changing, and new things are adding up daily. Because of which the developers should learn new things every day and can’t just rely on their older knowledge.
  2. Several React users think they are uploading poor documentations.
