Why Should You Use React? Pros And Cons Of Using React

If you’re unfamiliar with React, you’re probably wondering why it’s so popular and why you should use it in your applications. If so, you’ve come to the right place. Let’s talk about why React.js is so great and why you should use it in your projects by studying its pros and cons.

History of React.JS

React.js was created by Facebook in 2011 for their own use. As you may be aware, Facebook is one of the world’s most popular social networking sites.

Instagram, a subsidiary of Facebook, started using it in 2012.

React.js was open-sourced by Facebook in 2013. The developer community initially rejected it because it combined Markup and JavaScript in a single file. However, as more people tried it, they began to embrace the component-centric approach to separating concerns.

Many large corporations began using React.js in production environments in 2014. React.js began using Semantic Versioning in version 15 in 2016. This also contributed to the developer community’s perception that React was more stable.

Many Fortune 500 companies now use React.js. Facebook employs full-time React developers. They release bug fixes, enhancements, blog posts, and documentation on a regular basis.

What Are the Benefits of Using React?

You’re probably wondering why you’d want to use React.js. After all, as the use of JavaScript has grown in recent years, we now have a plethora of alternatives on the market, such as Angular and Vue.js. So, why do we use React?

React is a Flexible library

React is extremely adaptable. Once you’ve mastered it, you can use it to create high-quality user interfaces on a wide range of platforms. React is NOT a framework; it is a library. React has evolved into such a remarkable tool thanks to its library approach. React was created with a single goal in mind: to create web application components. A React component in your web application can be anything like a Button, Text, Label, or Grid.

However, as React’s popularity has grown, so has its ecosystem, which now covers a wide range of use cases.

React also supports server rendering of its components through the use of tools such as Next.js.

React has a great Developer Experience

When your team begins coding in React, they will fall in love with it. The combination of rapid development and React’s small API results in an excellent developer experience.

The React API is extremely simple to grasp. There are only a few concepts to learn. Here’s an example of a React Component.

All you have to do is import the React library. The Message component accepts props (input) and returns JSX.

JSX is a special syntax that looks like HTML and converts React’s API calls to HTML. React takes the inverse approach. It employs HTML (JSX) within JavaScript. This approach appeals to me because it allows you to work with only JavaScript and HTML, although it has its own pros and cons.

React has Meta Support Community

React is widely used in Facebook’s app, website, and Instagram. That is why Facebook is so dedicated to it. In their production environment, they use over 50k React components. On GitHub, the top four React contributors are all full-time Facebook employees.

Also, the React team maintains a blog that consistently gives you details for each release. React also has big community support. It has a large and active community, with over 194k Stars and forks around 40k on its GitHub Repository. It is one of the top five GitHub repositories.

Pros & Cons of ReactJS


  • Simple to Understand and Apply:- ReactJS is much simpler to learn. It includes a wealth of documentation, tutorials, and training materials. Any developer with a JavaScript background can quickly understand and begin creating web apps with React.
  • Reusable Components:- A ReactJS web application is composed of several components, each with its own logic and controls. These components are in charge of generating a small, reusable piece of HTML code that can be used wherever it is required. The reusable code makes it easier to develop and maintain your apps.
  • Enhancement of Performance:- ReactJS addressed this issue by introducing virtual DOM. The React Virtual DOM is a representation of the web browser’s DOM that exists entirely in memory. As a result, when creating a React component, we avoided writing directly to the DOM. Instead, we’re creating virtual components that will react and become the DOM, resulting in smoother and faster performance.
  • SEO friendly:- ReactJS solves this issue, allowing developers to be easily found on search engines. This is due to the fact that React.js applications can run on the server, and the virtual DOM will render and return to the browser as a standard web page.


  • Inadequate documentation:- It is yet another disadvantage of constantly updating technologies. React technologies are updating and accelerating at such a rapid pace that there is no time to create proper documentation. To overcome this, developers write their own instructions as new releases and tools are added to their current projects.
  • React is Based on third-party libraries:- React is “just a library,” and there are no official libraries to handle common frontend features such as routing, HTTP requests, and so on.
