Home in Jquery
Sure! Here's a quick but clear overview about jQuery, especially useful if you're just starting with it ?
What is jQuery?
jQuery is a fast, small, and feature-rich JavaScript library that simplifies things like:
HTML DOM traversal and manipulation
Event handling
AJAX calls
Animations
Instead of writing complex vanilla JS, jQuery helps you write less and do more!
Why Use jQuery?
| Vanilla JavaScript | jQuery Equivalent |
|---|---|
document.getElementById("btn") | $("#btn") |
element.addEventListener("click", ...) | $("#btn").click(...) |
fetch('url').then(...) | $.ajax({...}) |
So basically: less code, cleaner syntax, and cross-browser compatibility.
How to Include jQuery
Add this in your HTML or before :
<script <button "#helloBtn").click(function() { alert("Hello from jQuery!"); });script>
Hide/Show Elements
"#hideBtn").click(function() { $("#message").hide(); // You can also use .fadeOut() });script>
AJAX Example
$.ajax({ url: "data.php", method: "GET", success: function(response) { console.log("Server says:", response); }});
When to Use jQuery

Quick projects
Legacy apps
Simple DOM tasks or AJAX requests
