Introduction to jQuery and React Comparison

Recently, I decided to weigh in on the comparison between jQuery vs React. It’s important to clarify that they serve different purposes, so a direct head-to-head comparison might be misleading. So instead, I’ll explore how each technology suits distinct web development needs. In some cases, these two popular JavaScript libraries work together as a proper team.

Both React and jQuery use Javascript and have been pivotal in shaping the web development world. According to the StackOverflow Survey, these libraries have consistently ranked among the most popular web frameworks and technologies. However, their trajectories have differed. jQuery has been around for almost twenty years, but saw a significant drop in interest, declining from 34% to 15% in just two years (2021 vs 2023). Interestingly, in 2024, it grew once more to reach 21%.

React on the other hand remained popular since 2021, continuing to garner significant interest among developers.

Let’s delve deeper into each technology, understanding its core functionalities, and strengths. Learn how they can be effectively utilised in various development scenarios.

Understanding jQuery

jQuery is a library released in 2006 by John Resig. It was designed to simplify the complexities of JavaScript tasks, particularly in DOM manipulation and event handling. Its primary purpose was to make it easier for web developers to write JavaScript that works across different browsers. It helped alleviate the pain points of cross-browser inconsistencies.

Key jQuery Functionality

DOM Manipulation: jQuery provides an intuitive and straightforward API for selecting and manipulating DOM elements. The $ selector syntax allows javascript developers to quickly find and alter elements on a web page. It is one of its most celebrated features.

Event Handling: With jQuery, handling events such as clicks, key presses, and mouse movements is simple. It abstracts the differences in how browsers handle events, providing a unified way to manage user interactions.

AJAX: jQuery’s AJAX methods facilitate asynchronous HTTP requests, enabling developers to load data in the background without refreshing the entire page.

Cross-Browser Compatibility: One of the core strengths of jQuery is its ability to handle cross-browser inconsistencies. It smooths out the differences between browsers, ensuring that the same code works consistently across various environments.

Animation: jQuery offers a suite of methods for creating animations, making it easy to add visual effects like fading, sliding, and custom animations to web pages. This feature enhances user experience by adding dynamic content transitions.

Best Use Cases For jQuery

Simple Websites: jQuery library is ideal for simple websites that require basic interactivity without the overhead of a full-fledged JavaScript framework. Its lightweight nature makes it a good fit for these scenarios.

Adding Interactivity to Static Pages: For static pages that need a touch of interactivity, jQuery is a perfect tool. It can add dynamic elements such as image sliders, form validations, and interactive menus with minimal code.

Quick Prototypes: When speed is essential, and the goal is to quickly prototype a concept, jQuery provides the necessary tools to build functional mock-ups rapidly. Its ease of use and extensive documentation make it an excellent choice for prototyping.

Rich Form Handling: jQuery is used to simply the creation of dynamic, interactive forms with real-time validation, conditional fields, and AJAX submissions. For example, a registration form that dynamically displays additional fields based on user input can be implemented quickly with jQuery.

jQuery’s simplicity and powerful features have made it a staple in web development for many years. And till this day, despite the emergence of modern frameworks, it remains relevant, especially in scenarios where its strengths are most needed.

Understanding React js

React is a library for building user interfaces, developed by Facebook and released in 2013. Its core purpose is to provide a declarative and efficient way to build reusable UI components, making it easier to manage the state and rendering of complex applications.

Key React js Features

Component-Based Architecture: React promotes building user interfaces using reusable components. Each component represents a self-contained piece of the UI, making it easier to manage and maintain large applications. Components can be nested, managed, and handled independently, promoting a modular approach to development.

Virtual DOM: The Virtual Document Object Model is a lightweight copy of the actual DOM. React uses a virtual dom to optimise updates and rendering. When the state of a component changes, React updates the Virtual DOM first, compares it with the real DOM, and only makes necessary changes. This process, known as reconciliation, makes React applications fast and efficient.

State Management: State management is crucial in React library. Each component can have its state, which determines how it renders and behaves. React’s state management, coupled with libraries like Redux or Context API, allows for handling complex state logic and sharing state across components seamlessly.

Unidirectional Data Flow: React comes with an unidirectional data flow, meaning data flows in one direction from parent to child components. This makes it easier to debug and understand how data is being passed through the application, leading to more predictable and maintainable code.

JSX: React uses JSX, which is a syntax extension that allows developers to write HTML-like code within JavaScript. This makes it easier to visualize the structure of the UI directly within the JavaScript code, improving readability and developer productivity.

Best Use Cases For React

Dynamic Content Applications: For applications that need to update content based on user interactions or real-time data frequently, React’s efficient rendering and state management capabilities shine. This makes it perfect for live chat applications, real-time data dashboards, and news feed applications.

Toolbox team wanted to use modern technology that would provide a smooth user experience and enable them to build unified branding across their products. React.JS was a natural choice for the development.

Complex User Interfaces: React is better suited in building applications with complex user interfaces, where multiple interactive elements need to be managed effectively. This includes e-commerce platforms with features like product carousels, filtering options, and user reviews, which require a dynamic and interactive UI.

Enterprise Applications: Many developers prefer React for building large-scale enterprise applications that demand robust and maintainable codebases. Examples include customer relationship management (CRM) systems, enterprise resource planning (ERP) systems, and internal dashboards, where a modular and maintainable approach is crucial.

PWAs: React gives the opportunity to create progressive web apps that offer a native app-like experience on the web, often combined with service workers. It’s ideal for offline-first applications and responsive web applications that work across different devices and network conditions.

Projects Built with Next.js: Next.js, built on top of React, enhances its capabilities with server-side rendering and static site generation. This makes it perfect for SEO-friendly websites, content-heavy blogs, and e-commerce sites with dynamic content that need to be indexed by search engines.

Striving to maintain velocity across multiple high-priority tasks, Amplience required a swift and efficient solution that would not compromise the quality of the developer guide, so they decided to develop their interactive guide with React.

The main differences between jQuery and react

The main difference between jQuery and React lies in their core purposes, approach, and focus.

Purpose Of jQuery vs React

jQuery simplifies JavaScript for DOM manipulation, event handling, and AJAX interactions while React offers a framework for building dynamic and interactive user interfaces with a component-based architecture.

Approach To Web Development With jQuery and React

jQuery is a feature-rich JavaScript library that makes it easier to work with the DOM and handle events across different browsers. And React abstracts the UI into reusable components and uses a Virtual DOM to efficiently update and render the interface.

Difference between React And jQuery In Focus

jQuery focuses on manipulating the DOM directly and enhancing interactivity with minimal setup whereas React is on building complex, state-driven UIs with a declarative programming style, making it easier to manage the state and behavior of applications.

Complementary Use in Projects: Real-World Scenarios Where Combining jQuery and React Makes Sense

Even though, or thanks to that they serve different purposes, React and jQuery are used as complementary libraries in different projects. Here are some of the examples:

Incremental Migration:

Scenario: A legacy web app that uses jQuery needs new features.

Approach: Use React to develop new, complex features while keeping the existing jQuery codebase for simpler interactions. This allows for a gradual transition to React without disrupting the entire application.

Higher Interactivity on Static Pages:

Scenario:
A static website requires enhanced interactivity, such as modal dialogues and form validations.

Approach: Implement jQuery for straightforward tasks like form validation and basic animations. Use React.js to build more complex components like dynamic content sections or interactive dashboards, ensuring a cohesive user experience.

E-commerce Platforms:

Scenario: An e-commerce site needs a robust product management interface while maintaining existing jQuery-based features.

Approach: Utilize React.js for the product management interface, benefiting from its efficient state management and component reuse. Keep jQuery for existing functionalities like image sliders and quick product view modals.

Content Management Systems (CMS):

Scenario: A CMS with an extensive jQuery codebase needs an upgraded user interface for better user engagement.

Approach: Integrate React.js for the new user interface components, such as content editors and media galleries, while retaining jQuery for legacy features like form submissions and simple DOM manipulations.

By combining these popular javascript libraries, projects can leverage the strengths of both technologies, ensuring a smooth transition from legacy practices to modern development standards without sacrificing functionality or performance.

Why Many Big Brands Decide to Move from jQuery to React

Many big brands initially adopted jQuery due to its simplicity and ability to handle basic web development tasks efficiently. However, in time, both the world and the users expect more complex solutions. The modern web is characterised by dynamic, interactive, and often complex applications. Users expect seamless experiences across various devices, from smartphones to desktops. Key trends driving this evolution include:

• Real-time updates: Data is frequently refreshed without full page reloads, providing users with up-to-date information.
• Mobile-first design: Websites are optimised for smaller screens first, ensuring optimal user experience on mobile devices.
• Rich user interfaces: Complex interactions, animations, and visual effects are common.
• Performance optimization: Fast loading times and smooth interactions are essential.
• Thriving community: React is an open-source framework, and its popularity guarantees plenty of resources and talent for developing your React web app.

jQuery, while useful for basic DOM manipulation and event handling, falls short in meeting the demands of the modern web. It is primarily designed for manipulating static HTML documents and lacks the features necessary for building complex, dynamic applications. Its limitations include:

• DOM manipulation: While jQuery excels at this, direct DOM manipulation can be inefficient for large-scale applications.
• Lack of component-based architecture: jQuery doesn’t provide a structured way to build reusable UI components.
• Limited state management: Managing application state becomes challenging as complexity grows.
• Performance issues: Direct DOM manipulation can lead to performance bottlenecks in complex applications.

In contrast, modern frameworks like React, Angular, and Vue address these challenges. They offer features like component-based architecture, efficient state management, virtual DOM, and performance optimizations that are essential for building high-quality web applications.

Conclusion – JQuery and React Development

While both jQuery and React have their place in modern web development, the choice between them depends on project requirements, team expertise, and long-term goals. Your project can benefit from jQuery directly, thanks to its functionality, while the ability to learn React quickly makes it a popular choice. For simple websites and quick prototypes, jQuery remains a viable option.
