React Features

Currently, ReactJS gaining quick popularity as the best JavaScript framework among web developers. It is playing an essential role in the front-end ecosystem. The important features of ReactJS are as following.

  • JSX
  • Components
  • One-way Data Binding
  • Virtual DOM
  • Simplicity
  • Performance
  • Declarative UI
  • Component Based Architecture


JSX stands for JavaScript XML. It is a JavaScript syntax extension. Its an XML or HTML like syntax used by ReactJS. This syntax is processed into JavaScript calls of React Framework. It extends the ES6 so that HTML like text can co-exist with JavaScript react code. It is not necessary to use JSX, but it is recommended to use in ReactJS.


ReactJS is all about components. ReactJS application is made up of multiple components, and each component has its own logic and controls. These components can be reusable which help you to maintain the code when working on larger scale projects.

One-way Data Binding

ReactJS is designed in such a manner that follows unidirectional data flow or one-way data binding. The benefits of one-way data binding give you better control throughout the application. If the data flow is in another direction, then it requires additional features. It is because components are supposed to be immutable and the data within them cannot be changed. Flux is a pattern that helps to keep your data unidirectional. This makes the application more flexible that leads to increase efficiency.https://imasdk.googleapis.com/js/core/bridge3.521.0_en.html#goog_1541476308

Virtual DOM

A virtual DOM object is a representation of the original DOM object. It works like a one-way data binding. Whenever any modifications happen in the web application, the entire UI is re-rendered in virtual DOM representation. Then it checks the difference between the previous DOM representation and new DOM. Once it has done, the real DOM will update only the things that have actually changed. This makes the application faster, and there is no wastage of memory.


ReactJS uses JSX file which makes the application simple and to code as well as understand. We know that ReactJS is a component-based approach which makes the code reusable as your need. This makes it simple to use and learn.


ReactJS is known to be a great performer. This feature makes it much better than other frameworks out there today. The reason behind this is that it manages a virtual DOM. The DOM is a cross-platform and programming API which deals with HTML, XML or XHTML. The DOM exists entirely in memory. Due to this, when we create a component, we did not write directly to the DOM. Instead, we are writing virtual components that will turn into the DOM leading to smoother and faster performance.

Declarative UI

This feature makes React code more readable and easier to fix bugs. React JS is the best platform to develop UIs that are both exciting and engaging not just for web apps, but mobile apps as well.

Component Based Architecture

This simply means that the user interface of an app based on React JS is made up of several components, with each of them having its particular logic, written in JS. Due to this, developers can relay the data across the app without the DOM being impacted. React JS components play a huge part in deciding the app visuals and interactions.

After this React JS introduction, I think you would have at least a basic understanding of this platform. Let’s move further to the pros and cons of this platform.

Advantages of React JS

The main reason for the immense popularity of this platform is that there are many benefits of react js:

1. Short Learning Curve

In comparison with other frameworks, React JS is very easy to learn, pushing it up the popularity charts; this allows developers to complete their projects in record time.

Businesses can be up and running online in minimal time.

2. Enables Building Rich UI

The UI of an app is extremely important nowadays; an app with a great UI that offers an exciting browsing and shopping experience to users definitely has much better chances of succeeding than one with a poor interface.

You can easily develop engaging interfaces with superior quality using React JS – chiefly due to the declarative components feature.

3. Facilitates Creation of Custom Components

JSX enables the creation of unique components to suit your requirements; they accept HTML coding and eases the rendering of sub-components.

It also facilitates the development of apps that are high volume, and helps to create React Element trees from HTML mockups.

4. It Boosts Developer Productivity

Thanks to the feature of reusing components, enables developers to redistribute the same digital objects. Therefore, even with frequent updates or modification of components that usually impact others, in React it does not become problematic for developers. Developers can just add text fields, buttons, or other simple elements and in the next stage, place them in wrapper components, and eventually to the root element.

The advantage here is that it offers improved maintenance and growth of the code since every React component has a unique internal logic that can be easily operated.

5. Quick Rendering

You need to define the app structure at the outset if you are developing a complex, high-load application.

It is here that the virtual DOM feature becomes valuable; the DOM structure is like a tree. This means that a small edit made at a top-level layer can hit the app UI hard. Thanks to virtual DOM, all changes can be first tested in it to determine the risk level with every modification before finalizing it.

This way, developers can guarantee superior UX and high performance of the app.

6. SEO-Friendly

For any app to do well, it is important that search engines like it; two factors are critical for apps: fast load time and rendering. If both these boxes are ticked, your app will rank higher on Google result pages.

The super-fast rendering feature of React brings down the load time of the page drastically, enabling businesses to get their apps ranked on the first page of Google search.

7. Helpful Developer Toolset

Facebook has included several developer tools for React and Chrome in the react js framework, and they help developers immensely in discovering parent and child components, observe their hierarchies, and examine their present state, and so on.

Through self-learning, developers will be able to use the emerging technologies in actual, live, projects.

8. Enhanced Code Stability

The downward data flow in React Js ensures that the parent structure is not impacted by changes made to the child structure .To change an object, the developer only has to edit its states and make appropriate modifications; in this manner, only a particular component will be updated while the others remain unchanged.

Consequently, there is better stability of code, and the app performance is very smooth as well.

9. Robust Community Support

There are innumerable React developers and who upload text and video tutorials online, answer queries on various forums and QA sites, and so on. They contribute towards improving the framework and making it even easier for other developers.

Disadvantages of React JS

Just like with every platform or framework, in spite of its numerous benefits, React JS does have some disadvantages.

Fortunately, they are very few in number. They are:

  • Lack of adequate documentation – in spite of there being a large community of React users and developers, there is a need for more documentation.
  • Only covers User interface – it is not possible to develop the entire application using only react js; we need to use other languages as well.
  • High pace – the development of applications based in React is very fast, and it can put a lot of pressure on the developer.
  • Migrating data from React Js can be time consuming and cumbersome; if you are unsure about the app’s future, you may have to go in a different direction for your frontend framework.
  • Setting up React can take more time than other popular frameworks like Vue

When to Use React JS?

Now that we have read about React JS basics, its pros and cons, let us move ahead and see what is React JS used for. While it’s not exactly a one-size-fits-all solution, there are plenty of react js use cases.

This framework is especially ideal for:

  • User friendly, fast, and responsive single page applications
  • Creating interactive elements within any UI
  • To develop components for high-volume, high performing apps
  • Developing quick loading web apps
  • Creating mobile apps in native platform
  • Ensuring stable and steady coding
  • Creating apps that are SEO friendly
  • Making scalable apps where you may need to frequently add new features

Why Choose React JS for Web Development?

We have already seen the humungous advantages offered by React JS, and those are the very reasons why you should choose react js for developing web apps and mobile applications. Let’s do a quick recap of those benefits:

  • It’s easy to learn
  • You can create engaging interfaces
