jQuery and React are the two most popular JavaScript libraries for front-end development in the world, according to Stack Overflow’s latest Global Developer Survey. However, jQuery’s popularity is more substantial among professional developers than among those getting started with coding

New coders likely prefer React because jQuery emerged in an era before many of the significant advancements in web development occurred. This puts jQuery at a disadvantage in specific projects requiring modern features. 

But whether to choose jQuery or React isn’t so easy to answer. 

Let’s take a deep dive into the background and use cases of these popular JavaScript libraries so you can decide which is best for you.

An overview of jQuery and React 

Facebook introduced React in 2009 as a front-end JavaScript framework to alleviate many of the challenges that front-end developers were experiencing in those days. It was hoped that React would greatly simplify the development of single-page applications, or SPAs. 
jQuery is an older utility library that provides quick solutions for simple problems. Whereas React is a framework dedicated to building user interfaces quickly, jQuery serves more as an all-around Swiss Army knife toolkit that helps make JavaScript developers’ lives easier. 
JavaScript is much easier to work with today, especially since ECMA International—the body regulating JavaScript standards—released ECMAScript 6, the 2015 standard for JavaScript, commonly known as EC6. 
EC6 introduced fundamental changes to JavaScript that reduced the need for many of the solutions provided by jQuery. However, a vibrant ecosystem and a plethora of third-party libraries had arisen by then, cementing jQuery’s position as an integral part of many web applications. 
jQuery also offers sophisticated and intuitive extension methods to query the DOM (Document Object Model) that JavaScript lacks, further ensuring that JavaScript developers continue to use jQuery. 
Unfortunately, React and jQuery don’t work seamlessly together. Although it’s possible to use React and jQuery in the same project through workarounds and careful planning, it isn’t recommended. Developers typically use jQuery and React in the same codebase only when an exceptional reason exists, such as a large legacy codebase that needs to be maintained. 
Because React and jQuery serve entirely different purposes, choosing either depends specifically on the objectives of your project. 
Popular front-end JavaScript frameworks such as React, Vue, and Angular have rendered many of the original reasons for choosing jQuery obsolete. 
For straightforward web pages or web apps, jQuery remains an excellent choice, especially if you don’t have extensive experience with any of the above front-end frameworks. 
React typically makes more sense for large-scale applications. 

Different purposes

jQuery was developed as a fast, small, feature-rich JavaScript library, primarily designed to simplify tasks like HTML document traversal, manipulation, event handling, and animation. 
For example, jQuery lets JavaScript developers execute many complex tasks in a single line of code. The following JavaScript code sample to change the CSS of all paragraphs in an HTML document requires a mind-boggling 33 lines of code.

Achieving the same result using the jQuery library requires only a single, intuitive line of code:

Converting that single line of jQuery code into React wouldn’t be a fair comparison. Yes, the resulting code in React is more complex. But the comparison is moot: CSS standards have advanced so much since the release of jQuery that we can now achieve the same result without using any code. 
Specifically, the ability to add fade-ins was added directly to the CSS standard in 2009. Browser support for CSS transitions and animations lagged, but all major browsers supported it a few years later. Programmers no longer needed to use JavaScript code to create fade-ins but could simply add the relevant CSS, and the browser took care of the rest: 
jQuery was designed to solve challenges that developers were experiencing, but many of those challenges no longer exist, because technology has advanced. 
Facebook created React primarily to facilitate building user interfaces, especially complex ones that provide an excellent user experience. Getting to the point of generating simple animations in React requires that you scaffold the basic React app first. That takes some initial work. Once the scaffold exists, React lets you do many more complex things easily that jQuery can’t. 
The rule of thumb could be: 
  • For quick JavaScript solutions in existing projects, use jQuery, because of its ease of use. 
  • For building an entire app from scratch, especially large applications, consider using React. 

DOM manipulation

React uses a virtual DOM, while jQuery works with the traditional DOM. Both choices have pros and cons. 
React’s preference for a virtual DOM is also a significant difference between React and Angular—Google’s open-source front-end framework. 
The React library carries out all DOM element tasks in memory. When those tasks are complete, it pushes the changes to the physical DOM. Working with the real DOM, changing an element means changing the physical structure for every step, leading to potentially slower code. 

Community and ecosystem

React has a rich ecosystem of React libraries to speed up development. It also has a far greater number of npm packages than jQuery. However, that doesn’t necessarily mean that jQuery has fewer third-party libraries to support it. 
jQuery predates the widespread adoption of npm—the Node Package Manager, a package manager used to install and manage software packages or libraries used in JavaScript development. 
Extending jQuery functionality is typically done by adding jQuery plug-ins through an additional
