Before React, before Vue, before everything became "modern JavaScript," there was jQuery – the library that made developers say, "Wow, this is so much easier!"
Even though JavaScript has evolved, jQuery still holds a special place in web development. In this guide, we’ll take a fun and practical dive into what jQuery is, why it was a game-changer, and how you can still use it today (yes, it’s still relevant!).
What is jQuery?
jQuery is a fast, small, and feature-rich JavaScript library that simplifies HTML document manipulation, event handling, animation, and AJAX interactions with an easy-to-use syntax.
Why Was jQuery So Popular?
Simplifies DOM manipulation – No more document.getElementById() chaos. Cross-browser compatibility – It worked even when browsers were unpredictable. Super easy animations – Because who doesn’t love smooth effects? AJAX made simple – Fetching data without breaking a sweat.
Getting Started with jQuery
To use jQuery, you can include it via a CDN:
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
Or you can download and host it yourself (but why complicate life?).
jQuery Basics (a.k.a. JavaScript on Easy Mode)
1. Select and Manipulate Elements
Instead of doing this in vanilla JavaScript:
document.getElementById("myText").innerText = "Hello, World!";
You can do this in jQuery:
$("#myText").text("Hello, World!");
2. Handling Click Events
Instead of:
document.getElementById("myButton").addEventListener("click", function() {
alert("Button clicked!");
});
Use jQuery:
$("#myButton").click(() => alert("Button clicked!"));
So much cleaner, right?
3. Adding/Removing Classes
$("#myDiv").addClass("highlight");
$("#myDiv").removeClass("highlight");
4. Animations (Because Fancy is Fun)
$("#myDiv").fadeOut(1000).fadeIn(1000);
5. Making an AJAX Request Like a Boss
$.ajax({
url: "https://api.example.com/data",
method: "GET",
success: function(data) {
console.log("Data received:", data);
},
error: function(error) {
console.error("Oops!", error);
}
});
Is jQuery Still Relevant in 2025?
Yes and no. While modern JavaScript frameworks have taken over, jQuery is still widely used in legacy projects, WordPress sites, and quick prototyping. If you work in web development, chances are you’ll encounter jQuery at some point.
Conclusion
jQuery may not be the new kid on the block, but it’s still a powerful tool for web developers. Whether you’re maintaining an old project or just want to simplify JavaScript, jQuery has your back. Happy coding!
