jQuery VS JavaScript Language

#About Know JavaScript Language -

JavaScript is an interpreted, lightweight programming language. It is intended for the development of network-centric applications. It works in tandem with and complements Java. Because JavaScript is interwoven with HTML, it is incredibly simple to use. It's free to use and cross-platform.
When compared to JavaScript, jQuery requires less code testing and less code to achieve the same purpose. Change the font size, background colour, and so forth and Some difficulties, like as cross-browser compatibility, are still being worked out in JavaScript. This could be due to web browser developers' poor JavaScript implementation techniques.
See below example of JavaScript language code-

document.getElementById("button")
        .addEventListener('click', function(){ 
          alert("Hello, How are you!");
      });

What is the difference between JavaScript and jQuery code?

#About Know jQuery Language -

jQuery facilitates HTML page traversal, event handling, animation, and Ajax interactions and JQuery is essentially not a separate programming language, but rather a JavaScript library. It's one of the most popular JavaScript libraries since it's simple to use and powerful.
Many programmers are perplexed by these languages and believe they are two distinct programming languages when, in fact, they are the same. JQuery has been optimised to execute a wide range of scripting functions, and it can do so with just a few lines of code.
See below example of jQuery language code-

$( document ).ready(function() {
$('#button').click(function(){ 
    alert("Hello, How are you!"); 
});
});
