In the fast-moving world of web development, choosing the right technology stack means digital success. Choosing the right framework that will satisfy current needs and make sure there is scalability and further growth in several years—no one can overestimate this paramount decision for entrepreneurs today. There is one of the most debated comparisons in this space: ReactJS vs jQuery. While both have been really very important for carving out the web as we know it today, the question begs: Is ReactJS the future? And should entrepreneurs look to move away from jQuery?
This blog from Inwizards, a leading ReactJS Development company attempts to answer these questions by looking at the intrinsic differences between ReactJS and jQuery and their respective strengths and limitations, and why ReactJS is fast getting popularity as being the future of web development.
What is jQuery?
In 2006, jQuery was the solution—an agile, little, full-of-features JavaScript library focused on making the process of writing JavaScript less painful. It presented a clean API, easy to use, which can be used for functions on several browsers, solving compatibility issues, hence making DOM manipulation, event handling, and animation easy. jQuery changed web development at that time in such a way that now a developer can create dynamic interactive web applications without having to code thousands of lines of JavaScript from scratch.
Some key features of jQuery include:
- Cross-browser compatibility: jQuery’s ability to handle different browsers made it a favorite among developers.
- DOM manipulation: Simplified ways to interact with and modify the HTML DOM.
- Event handling: Easy handling of events like clicks, hover, and form submissions.
- AJAX support: Simplified methods for making asynchronous requests.
Common use cases for jQuery include:
- Adding interactive elements to websites such as sliders, modals, and form validations.
- Simplifying the handling of HTML events across different browsers.
- Performing AJAX calls to update parts of a web page without reloading.

What is ReactJS?
ReactJS is an open-source JavaScript library developed and maintained by Facebook. It is meant for building user interfaces, considering single-page applications in which data will change dynamically on the page without the page reload. ReactJS, being built in 2013, has a rather different approach toward front-end development and cares about the creation of reusable components that can manage their independent state and can be composed together to build complicated UIs.
Key features of ReactJS include:
- Component-based architecture: Reusable components that manage their own state and can be composed to create complex UIs.
- Virtual DOM: ReactJS uses a virtual DOM to improve performance by updating only the parts of the DOM that have changed.
- One-way data binding: Ensures that the data flow is consistent and predictable, making debugging easier.
- JSX: A syntax extension that allows HTML to be written within JavaScript, improving code readability and ease of use.
Common use cases for ReactJS include:
- Building single-page applications (SPAs) where performance and dynamic updates are crucial.
- Developing complex web applications with multiple interactive components.
- Creating mobile applications using React Native, which shares the same foundational principles as ReactJS.

ReactJS vs jQuery: A Comparative Analysis
Performance
One of the major differences between ReactJS vs. jQuery is performance. jQuery is directly related to DOM; hence, any change made bears a re-rendering responsibility of the entire DOM onto the browser, which in fact slows down performance, especially for large applications.
On the other side, ReactJS uses a virtual DOM. Now, if a change has occurred, ReactJS will update the virtual DOM first and later compare the virtual DOM with the actual DOM to figure out what has been changed. Now it updates only those parts of DOM that have changed. This results in faster rendering and ultimately better performance, especially in applications with high-driven user interfaces.
For instance, with a big e-commerce site that has a lot of product listings, filters, and interactive elements, using jQuery might result in several milliseconds of latency whenever the state of these elements is changed. On the other hand, ReactJS is engineered for better handling of updates, giving a very good experience to users in general.

Scalability
Scalability is also an important point where ReactJS outshines jQuery. This jQuery approach may fit in the case of small- to medium-sized applications, but as the application grows, the codebase may become very difficult to manage. jQuery doesn’t support modularity or the reusability of code, which innately makes it a tough task to scale projects as more features are added.
However, ReactJS has a component-based architecture. It is made for scalability because it is a self-managing entity responsible for its own state and rendering logic. This modularity makes it easier to manage really big projects because a single component can be reused in different parts of an application. New ones can be added without affecting the existing code base so that the project can thus stay maintainable and scalable with the application growth.
For instance, if a startup began with a small web app, building and integrating new components using ReacJS will allow for the extension of features with ease, considering there is little refactoring of the existing code.
Developer Experience
What is most important in this case is the difference in developer experience when using ReactJS vs. jQuery. jQuery, for example, is simplified and easy to use. The syntax is very simple, and a developer may do much with a few lines of code. The ease of use has brought limitations to its maintainability and scalability, especially on growing applications.
One of the major reasons behind ReactJS’s popularity is that even though the ideas like JSX, state management, and component lifecycle could make its learning curve steeper than that of Vue.js, it will really be able to offer a much richer developer experience in the long term. The very rich ReactJS ecosystem, like Redux for state management and React Router for navigation, equips the developers with great tools to effectively build complex applications.
One-way data binding by ReactJS makes the flow of data within the application predictable, hence reducing the occurrence of bugs and making debugging easier. Moreover, it is one of the strongest choices for a developer targeting the building of robust applications, thanks to its extensive community support, detailed documentation, and plenty of online resources.
Community and Support
Well, both ReactJS and jQuery have huge communities, although the nature of support is quite different. jQuery was first introduced back in 2006 and thus has a huge number of plugins, tutorials, and community-driven support. However, over the years, with further evolution of the web development landscape, the jQuery community today is relatively less active, and creation of new resources has reduced.
On the other hand, ReactJS stands at the very forefront of modern web development. It has a huge active community behind it that’s ever-growing, and thus includes a rich ecosystem of libraries, tools, and frameworks extending ReactJS’s capabilities. Its vibrant community makes sure ReactJS stays relevant and continues to evolve according to the most recent trends in the industry.

Why Entrepreneurs Should Consider Moving Away from jQuery
Technological Advancements
The scene of web development has dramatically changed over the last decade, with new technologies and frameworks born out of the urge to overcome the shortcomings and limitations of older solutions like jQuery. ReactJS is the middle ground in this shift towards a modern way of building user interfaces, going hand in hand with the present trends in web development.
One of these trends is the appearance of Single Page Applications, which provide smoother and more dynamic user experience because they load content in a dynamic way, avoiding page refreshes. ReactJS is developed for work in conjunction with SPAs, so this is a perfect choice for entrepreneurs who are reassured in delivering top-notch web applications.
For instance, the flexibility of ReactJS goes all the way to web development. Being the parent to the framework, ReactJS gives developers the capability of building mobile applications just the same way, and in some cases, sharing code between the web and mobile applications. This makes ReactJS future-proof and a worthy investment for businesses striving to build their digital presence on multiple platforms.
Long-Term ROI
ReactJS can produce very high long-term returns on business investments. While the investment in learning and implementing ReactJS may be higher than jQuery, benefits in performance, scalability, and maintainability more than compensate for that.
The component-based architecture of ReactJS means less time and effort must be put into the development of new features since the developer is allowed to reuse already written components and continue improving on them. This modularity gives easy maintenance of the codebase, reducing technical debt and chances of costly refactoring in the future.
Moreover, while web applications are growing bigger and more complex, performance improvements that ReactJS offers can lead to a better user experience, turning into higher user engagement and retention. These are some reasons for a better return on investment for businesses choosing ReactJS over jQuery.
Business Case Studies
A number of businesses have already made the successful shift from jQuery to ReactJS. For example, Airbnb—a web and mobile online marketplace on renting different categories of lodging—migrated from jQuery to ReactJS for performance and scalability in its platform. With this shift, they were able to create a more responsive user interface and thus increase user satisfaction and engagement.
Another example is Netflix, which allows front-end development to be performed using ReactJS to elevate the user experience for the web platform. Switching to ReactJS, Netflix could render a smoother and more dynamic interface with faster loading and performance across devices.
These case studies demonstrate real benefits which businesses can reap from transitioning from jQuery to ReactJS, thereby making a strong case for why entrepreneurs should consider this transition.

Practical Considerations for Migrating from jQuery to ReactJS
Migration Strategy
Migration from jQuery to ReactJS will require proper planning and execution. The following is a step-by-step method to easily shift a business:
- Assessment: Start by assessing your current application. It outlines the areas that have jQuery dependencies and defines your scope of migration.
- Componentization: The application is broken down into smaller, reusable components. You can start replacing jQuery functionality with ReactJS in a progressive manner.
- Parallel Development: Having jQuery and ReactJS run in parallel might be useful during a migration phase. This will ensure the addition of ReactJS components could be incremental and not affect any existing functionality.
- Testing: Testing of each ReactJS component as it gets integrated must be done at a very high level of granularity on how it works, and ensure regression is not introduced.
- Optimization: Once this is migrated, optimize your ReactJS components for performance. Take advantage of features that are provided out-of-the-box by ReactJS, among which the most important one is its Virtual DOM.
- Refactor: When the migration is over, refactor the codebase to make it independent of jQuery, for a clean and maintainable ReactJS codebase.
Challenges and Solutions
Though migrating from jQuery to ReactJS is not that easy, here are some common challenges in this regard:
- Learning Curve: ReactJS introduces new concepts like JSX, state management, and component lifecycle, which may be unfamiliar to developers accustomed to jQuery. Providing training and resources can help ease this transition.
- Compatibility Issues: Integrating ReactJS components into an existing jQuery-based application can lead to compatibility issues. Running the two in parallel during the migration can help mitigate these issues.
- Time and Resource Investment: Migrating to ReactJS requires an upfront investment in time and resources. However, this investment pays off in the long run through improved performance, scalability, and maintainability.
