For many years, jQuery was a staple of web development. It helped developers create complex JavaScript functions with simple and easy-to-understand lines of code. But times change, and so do the tools and methods we use. In this article, you will learn why jQuery is often redundant today, what modern alternatives exist, and what problems using jQuery brings with it.
TL;DR: jQuery is outdated. Modern JavaScript (ES6+) natively supports everything jQuery was used for. Frameworks like React, Vue, and Angular offer far superior component-based architectures. Even Bootstrap 5 dropped jQuery.
The Heyday of jQuery 🌸
jQuery was first released in 2006 by John Resig and quickly revolutionized the way developers wrote JavaScript. At a time when JavaScript was full of browser incompatibilities and complex syntax, jQuery offered a simplified and unified API. Within a few years of its release, jQuery became the dominant JavaScript library on the web.
According to a W3Techs survey, jQuery was used on more than 50% of all websites by 2012, and that number rose to over 70% by 2015. Features like DOM manipulation, event handling, animations, and AJAX requests were significantly simplified with jQuery, making it easy for developers to create interactive and dynamic web applications. The extensive plugin library made it possible to quickly and efficiently add additional features, making jQuery an indispensable tool in web development.
jQuery offered simplified syntax and smoothed over the differences between browsers. Features like DOM manipulation, event handling, animations, and AJAX requests were significantly simplified with jQuery.
// Example of jQuery DOM manipulation
$(document).ready(function(){
$("p").click(function(){
$(this).hide();
});
});
This simplicity and the extensive plugin library made jQuery an indispensable tool for web developers.
Why jQuery Is No Longer Necessary Today 🚫
With the evolution of JavaScript and the introduction of ES6 (ECMAScript 2015), many of the features jQuery offered were integrated into core JavaScript. Modern browsers now natively support functions that previously were only possible with jQuery.
DOM Manipulation
// With jQuery
$('#myElement').hide();
// With Vanilla JavaScript
document.getElementById('myElement').style.display = 'none';
Event Handling
// With jQuery
$('#myButton').on('click', function() {
alert('Button clicked!');
});
// With Vanilla JavaScript
document.getElementById('myButton').addEventListener('click', function() {
alert('Button clicked!');
});
AJAX Requests
// With jQuery
$.ajax({
url: 'https://api.example.com/data',
method: 'GET',
success: function(data) {
console.log(data);
}
});
// With Fetch API
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
These examples show that native JavaScript code is just as simple and understandable as jQuery code today.
Modern JavaScript Features That Replace jQuery ⚙️
The ECMAScript standards have introduced many features that were previously only available through jQuery. Here are some important examples:
Fetch API for AJAX Requests
Previously, jQuery was the best solution for AJAX requests. Today, you can use the Fetch API, which is part of the JavaScript standard.
Manipulating Classes and Attributes
jQuery made adding and removing classes and attributes easy. Modern JavaScript methods are just as easy and direct.
// With jQuery
$('#myElement').addClass('active');
// With Vanilla JavaScript
document.getElementById('myElement').classList.add('active');
// With jQuery
$('#myElement').attr('data-role', 'admin');
// With Vanilla JavaScript
document.getElementById('myElement').setAttribute('data-role', 'admin');
Animations
jQuery offered simple ways to create animations. With CSS transitions and animations as well as the Web Animations API, you can achieve similar effects without jQuery.
// With jQuery
$('#myElement').fadeOut();
// With CSS
document.getElementById('myElement').style.transition = 'opacity 0.5s';
document.getElementById('myElement').style.opacity = '0';
Traversing and Filtering
jQuery offered powerful functions for traversing and filtering the DOM. With modern JavaScript methods like querySelector and querySelectorAll, you can achieve the same results.
// With jQuery
$('ul > li:first-child').css('color', 'red');
// With Vanilla JavaScript
document.querySelector('ul > li:first-child').style.color = 'red';
These modern JavaScript features provide the same functionality as jQuery but are implemented directly in the browser and require no additional libraries.

The Problems with jQuery 🚫
Although jQuery had many advantages, there are several problems today that speak against its use:
Size and Performance
jQuery adds additional code that can increase the loading times of your website. In times when performance and loading speed are crucial factors for the success of a website, it is important to avoid every unnecessary library.
Dependencies
When you integrate jQuery into your project, you make yourself dependent on an additional library. This can become problematic when security vulnerabilities arise or the library is no longer actively maintained.
Modern Alternatives
Modern JavaScript frameworks and libraries offer more efficient and powerful solutions. React, Vue.js, and Angular provide integrated tools and features that go far beyond what jQuery can offer.
Best Practices
Web development has evolved, and today's best practices include the use of modular and component-based approaches. jQuery does not fit well into these modern development paradigms.

The Rise of Modern Frameworks and Libraries 🚀
Frameworks like React, Vue.js, and Angular have revolutionized the way we develop web applications. They offer component-based architectures and more efficient ways to manage application state. These frameworks rely heavily on modern JavaScript and no longer need jQuery.
React:
import React from 'react';
function MyComponent() {
const handleClick = () => {
alert('Button clicked!');
};
return (
<button onClick={handleClick}>Click me</button>
);
}
export default MyComponent;
Vue.js:
<template>
<button @click="handleClick">Click me</button>
</template>
<script>
export default {
methods: {
handleClick() {
alert('Button clicked!');
}
}
}
</script>
These frameworks are designed to create reusable components and efficiently manage complex applications. They also offer integrated solutions for things like routing and state management, going far beyond what jQuery can offer.
Bootstrap Without jQuery 📦
Another example of the move away from jQuery is the popular CSS framework Bootstrap. In its latest version (Bootstrap 5), jQuery was completely removed. This means all JavaScript components of Bootstrap are now written in pure JavaScript.
Marco Franke
Bootstrap Tooltip Example Without jQuery:
var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})
This shows that even large projects can do without jQuery and still remain powerful and user-friendly.

Conclusion ✨
jQuery was undoubtedly a significant tool that shaped web development in recent years. But with advances in native JavaScript features and modern frameworks, it is often no longer necessary today. By embracing these new techniques, you can not only future-proof your projects but also benefit from the performance and efficiency gains.
