What Is JQuery & Why’s It The Top JS Library In 2024?

The idea that JQuery is a legacy framework on its way to obsolescence needs to be clarified—so let's state the facts and clear up the ambiguity.

According to Stack Overflow's survey, 22.87% of developers still use JQuery, it's the third most popular web framework and one of the most starred repositories on GitHub.

Furthermore, it is used by more professional devs than all the other frameworks included in the survey, as can be seen in the graph below.

This article will cover the features of JQuery, the logic and reason behind the success of this framework, and how it stayed so vital all this time.

Introduction to JQuery

A brief overview of JQuery

JQuery is a fast and full-featured JavaScript library. It brought sanity to the world of frontend development by dealing with browser inconsistencies, providing an elegant API for dealing with AJAX and DOM manipulation, and introducing a robust plugin architecture.

The inception and evolution of JQuery

JQuery has matured and grown, becoming the de facto library for web development. JQuery's 3.5.1 release was a significant step forward, further solidifying its stronghold. It ironed out bugs, enhanced security, and kept JQuery relevant in the ever-evolving web landscape.

Understanding JavaScript and JQuery

What is JavaScript?

JavaScript is an object-oriented scripting language initially meant to handle small tasks in the Netscape Navigator browser, while Java took the heavy-duty server-side tasks.

JavaScript is the programming language commonly used on the web, allowing web devs to control webpage elements, create animations, and even handle web communication.

If HTML is the skeleton of a website a good idea is to think of the lightweight JavaScript library as the muscle that makes the web page dynamic and interactive.

What is JQuery and its relationship with other JavaScript libraries?

JQuery, on the other hand, is a free, fast, and concise JavaScript library created in 2006 by John Resig.

JQuery wraps many raw JavaScript functionalities in methods that you can call with simple syntax. It's not a language but a tool written in JavaScript that simplifies and streamlines JavaScript programming.

JQuery simplifies the HTML markup, document traversal, event handling, animating, and AJAX interactions for rapid web development.

You can think of JQuery as a Swiss Army Knife for JavaScript, bundling together everyday tasks into concise, cross-browser compatible code. It helps developers "write less, do more," as its tagline suggests.

For example, this task will be to select an HTML element with the ID "myElement" and change its text.

How JQuery simplifies JavaScript programming

Simply put, there is no JQuery without JavaScript.

Indeed, JQuery provides the framework that JavaScript devs can use to build web apps. However, the programming language, JavaScript is the main tool used to interact with this framework and make it operational.

Just as a builder uses his tools to construct buildings more efficiently, JQuery provides tools (in the form of prewritten functions and attributes) to JavaScript developers to write more efficient code.

JQuery simplifies the code to interact with HTML elements in documents, handle events, create animations, and develop AJAX applications.

Another critical aspect of JQuery is its philosophy of unobtrusive JavaScript—separating JavaScript functionality (the "behavior layer") from a web page's structure/content and presentation. This increases the page's accessibility, offers better maintainability, and speeds up page load times.

Learning JavaScript will help you appreciate the core programming concepts, and understanding JQuery will let you see how these concepts are implemented on the web.

Being comfortable with JavaScript before learning JQuery is essential as a developer. Therefore, getting a solid foundation in JavaScript first via Learn Enough's JavaScript course (with free sample chapters) is the perfect place to start.

Once you're comfortable with JavaScript, JQuery will be a piece of cake!

Key Features of JQuery

Let us discover some of the JQuery features and how they can help you in the web development process:

1. Easy DOM manipulation

JQuery can manipulate the Document Object Model easily. The DOM is a programming design for HTML and XML documents. It represents the structure of a document and allows programs to manipulate its form, style, and content.

JQuery provides a simple API for various DOM manipulations, like changing the range relative position of elements, modifying attributes, altering CSS, and more.

JQuery selectors are powerful tools that allow developers to select and manipulate HTML elements. They are based on the same selectors used in CSS, but with jQuery, you can use these selectors to perform a variety of tasks on the selected elements.

With JQuery's DOM manipulation methods, you can dynamically change your webpage's content.

Here's an example of how to change the text of an HTML element:

In this example, clicking the button will change the text in the paragraph from "Hello, World!" to "Hello, jQuery!".

2. Event handling made simple

Another powerful feature of JQuery is its simple and effective event-handling system.

In JavaScript, events are actions in the application you are programming. These events could be anything from a user clicking a button, a web page not loading, or an animation completing.

JQuery offers a great way to capture various events without the need to clutter your HTML code with event handlers.

It provides methods like click(), hover(), keypress(), blur(), and more that abstract the process of attaching event listeners to elements.

In this example, an alert box will pop up saying "Button clicked!" whenever the button is clicked:

In this example, the text color will change to red when the mouse hovers over the paragraph, and it will change back to black when the mouse leaves:

In this example, "Key pressed!" will be logged to the console every time a key is pressed in the input field:

In this example, when the input field loses focus (for instance, when the user clicks anywhere outside the input field), the text "Input field lost focus" will be displayed in the paragraph below the input field:

3. AJAX support

Asynchronous JavaScript and XML are web development techniques for creating asynchronous web applications.

Using AJAX, for example, you can exchange data with a server and update website sections without reloading the site or entire page.

Several methods for AJAX functionality allow you to load data from a server and place the returned data into the selected elements of your website or webpage seamlessly.

This makes working on websites with AJAX far less complex and minimizes the code you need to write.

4. Effects and animations

JQuery comes packed with several built-in animation effects that you can use on your websites.

You can create products like hiding/showing elements, fading in/out background color, sliding up/down, and custom animations with little to no effort.

These effects can create a dynamic and interactive user interface that enhances the user experience.

In this example, clicking the button will animate the green box. The box will increase in size and move to the right and down:

5. Cross-browser compatibility

JQuery provides cross-browser compatibility.

Each browser interprets JavaScript slightly differently, leading to inconsistencies in how your code behaves across different platforms.

That is why JQuery is perfect to save this issue.
