Why is ReactJS so bad?

Do developers actually hate ReactJS? Is this truly the worst JavaScript library around? Is there anything that could be done to improve its reputation? These three questions have been lingering in the air as developers debate the pros and cons of ReactJS.
The main challenge with ReactJS lies in its lack of a direct defining feature. Unlike traditional libraries like jQuery, ReactJS does not define specific styles, methods, or processes. Instead it is a collection of components that can be used independently. This has led to significant confusion for web developers, who need to understand each component before they can implement it. Without clear documentation of the components, developers may find themselves wrestling with incompatibilities across platforms and struggling to build a cohesive design. Additionally, as a one-size-fits-all library, ReactJS can take significant time to configure and customize.
In this article, you will learn more about the potential drawbacks of ReactJS and discover ways that developers can address these problems. We will cover various approaches to configuration and customization, and evaluate the overall performance of ReactJS in comparison to other libraries. Additionally, for those who are new to web development, there will also be an analysis of the best ways to learn ReactJS and how to make the most of this powerful tool. Through this discussion, readers will develop a deeper understanding of ReactJS and how to maximize its features to create successful web applications.Definitions:
ReactJS: ReactJS is an open-source, JavaScript library that developers use for building user interfaces (UIs). It is primarily used for developing single-page web and mobile applications. ReactJS follows a component-based architecture where code is split into small self-contained parts, and each part can be reused anywhere.
Bad: ReactJS is not universally considered to be “bad”, but rather is sometimes criticised for certain aspects of its design and implementation. For example, ReactJS heavily relies on JavaScript, which may be prohibitive for some developers. Additionally, it is sometimes argued that ReactJS is not well-suited for large applications. However, these criticisms are largely subjective, and opinions vary among developers.
In overall, ReactJS is an extremely popular and widely used JavaScript library, chosen by millions of developers for building powerful, fast UIs. Despite a few criticisms, ReactJS is a powerful and widely supported library that has been successfully used for a wide range of projects.

1. Reasons ReactJS is Bad

Reasons ReactJS is Bad

ReactJS is a library that allows developers to create interactive user interfaces, but there are several common criticisms against it. Many developers find ReactJS to be overly complex, with a steep learning curve and a large amount of code to memorize. ReactJS also requires a large set of external dependencies and higher system requirements than some other libraries.

Hard to Learn

One of the primary complaints against ReactJS is that it can be difficult and time-consuming to learn. ReactJS involves mastering multiple libraries, HTML and JavaScript components that can be difficult to keep straight. Additionally, new features are frequently added to ReactJS which can make mastering the library even harder.

Large Footprint

ReactJS is known to have a large codebase which is often referred to as a large “footprint.” The large footprint requires additional memory usage and a faster CPU in order for it to be able to manage all of the code. This can slow down browser load times and decrease the overall performance of the site.

External Dependencies

ReactJS also relies on a large stack of external dependencies. This means that multiple libraries have to be loaded in order to run ReactJS, which can also have a negative impact on performance. It also makes deploying and debugging ReactJS applications more complex.

Misuse of JavaScript

ReactJS also uses JavaScript in ways that some developers finds counterintuitive or unusual. It also mixes new and old JavaScript features together, which can make interpreting code more complicated. Additionally, the structure of code makes it difficult to predict the logic of the application.

List of Disadvantages

  • Hard to learn
  • Large footprint
  • Dependency on external libraries
  • Mixes old and new JavaScript features
  • Makes code difficult to understand
  • Requires a faster CPU to manage code
  • Slows down page loading

2. Pros and Cons of ReactJS

Pros of ReactJS

ReactJS is an open-source JavaScript library designed to help developers create interactive user interfaces for single page applications and mobile applications. ReactJS allows the use of reusable components and enables better collaboration between developers by making the code easier to troubleshoot and manage. The declarative component model makes it easy for developers to create components that either have a shared state or are stateless. This makes developing components easier and can save time. ReactJS allows users to manage complex UIs cleanly, making it easier to read and maintain. When coding, things such as data handling, UI feedback loops, and debugging are simplified as all the logic regarding components is handled internally. Finally, ReactJS can be used for both front-end and back-end development, leaning and simplifying the development process for many web-applications.

Cons of ReactJs

Despite offering great advantages, ReactJS also comes with some drawbacks. ReactJS is a client-side library which means that it is difficult to debug and can lead to unreadable code. ReactJS does not have a well-defined structure because it only acts as the V in MV. This makes it hard for developers to work together on the same code since the project’s overall structure is not clear. Additionally, ReactJS requires a lot of configuration to use and leverage properly. Third-party ReactJS libraries are constantly growing in number, making it hard to keep up with the latest trends and requirements. Finally, updating code can take longer than first intended, since developers often need to restart servers and projects when upgrading important files.

3. Alternatives to ReactJS

ReactJS is a popular framework for creating dynamic user interfaces. It is used by many companies for creating websites and mobile applications. However, some consider ReactJS to be a suboptimal choice for certain applications.

Lack of Control on What is Rendered

One of the main drawbacks of ReactJS is that it does not let developers control what gets rendered on the page. This is due to the fact that ReactJS uses a virtual DOM, meaning that when changes are made to the DOM elements, ReactJS will determine which parts to render and update. This means that developers have less control over the look and feel of the site.


Another potential issue with ReactJS is its performance. ReactJS can be slow, due to the virtual DOM, and the fact that it needs to constantly update and re-render elements. This can reduce the page speed over time, and lead to a negative user experience. Additionally, ReactJS requires more code to achieve the same result as other frameworks, increasing the size of the development bundle.
All in all, there are a few drawbacks to using ReactJS for certain applications. Developers should take these into account when deciding whether or not ReactJS is right for their application. Fortunately, there are plenty of alternatives to ReactJS that offer different features and functionality. For example, Angular is a popular framework that offers two-way data binding, while VueJS is also gaining traction in the web development community. Ultimately, it is up to the developer to decide which is the best framework for their particular application.
