Hey there Amrit,

jQuery is a fairly general topic, and it appears you are looking for information on starting out.  I will do my best to summarize anything on the topic without really diving into any particular area in great depth.

I think a good starting point is understanding exactly what jQuery is.  From the official website for jQuery:

jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.

Let's break that down real quick so we understand what they are saying.  jQuery is a JavaScript library, or in other words, jQuery is a bunch of JavaScript features that are super handy and already made for you.  This makes it so you don't have to reinvent the wheel every time any given person decides they need to do a common function in JavaScript.  jQuery in particular handles the manipulation of different CSS classes, as well as handles browser events like mouse clicks.  In short, jQuery allows for complex manipulation of the interface with simple code that is easy to follow.

A simple example of this is making text disappear when it is clicked on.  If you visit the live example at w3schools.com here you will see on the right hand side where you can click on the text, and it will disappear.  On the left is the code used to make this behavior happen.  If you notice the script code, we can follow the logic of the script.

<script>
$(document).ready(function(){
    $("p").click(function(){
        $(this).hide();
    });
});
</script>

What this code is doing is anytime someone clicks on any <p> element, that <p> element will get hidden.  While this is a very basic example, it gives you a general idea of how jQuery behaves.  Obviously making things disappear is a cool trick, but jQuery can do so much more than that.  If you are motivated to learn more about the subject, I highly recommend w3schools, as they are free to learn, provide live examples that you can manipulate, and even provide certification if you decide it's something you want to "prove" you can do to others (think employment).

If you visit https://www.w3schools.com/JQuery/jquery_intro.asp they will walk you through jQuery from basic concepts to advanced examples.  They highly recommend you have basic knowledge of CSS, HTML, and JavaScript before trying to dive into jQuery.  They also provide tutorials on these subjects if you find you need to brush up on CSS, HTML, or JavaScript.

I hope this has been a little helpful.  Please let me know if I can provide you anything else.

@Blaine has explained very well about jQuery.

Just an addition:

You can visit jQuery's official site: https://jquery.com/ where you can find the documentation of jQuery. For live examples, you can use w3schools. jQuery official site has got experts in it. For any kind of support, you can contact them. They'll response for sure. jQuery is additionally linked to some of members. You'll know about it once you visit the site.
