jQuery Introduction

jQuery is a fast, and lightweight JavaScript Library.
It simplifies HTML document traversal and manipulation, event handling, animation, and Ajax interactions.
Finally It minimizes the JavaScript code when we use jQuery.

HISTORY

Created by John Resig and released in 2006.
The primary goal of jQuery was to simplify client-side scripting and make it easier to handle HTML documents, interact with the DOM, and perform asynchronous operations.

Syntax of jQuery

For any jquery code to access a element or modify we use $() or jquery() function. Syntax $("h1").text("Modifed Text");

<html lang="en">

</head>
<body>
  <h1>Hello, jQuery!</h1>

  <script>
    // Your jQuery code goes here
    $(document).ready(function(){
      // jQuery code will run after the DOM is ready
