What is jQuery and why should it be used?

Jquery is a very old and popular JavaScript library. The jQuery library serves the purpose of performing the desired task without the clutter of code. Since jQuery is completely open-source and free technology, and due to the many advantages it provides, it is compared with many programming languages, but it's important to remember that jQuery is just a JavaScript library.

So, what advantages does jQuery provide us?

What are the Advantages of jQuery?

1. It works flawlessly in all browsers and corrects errors according to the browser (Cross-Browser feature).
2. Ease of learning, as stated in its slogan “Write less do more”
3. Easy and simple AJAX (Asynchronous JavaScript and XML) operations. (AJAX is a technique that allows us to create interactive web applications)
4. It is a small-sized library (does not slow down applications).
5. Offers built-in animation effects and features.

A Small Example…

The code that performs the same operation differs as follows.

JavaScript

function changeColor(color){
document.body.style.background = color;
}
Onload="changeColor('blue');

jQuery

$('body').css('background', '#0000FF');

Result

jQuery is a small-sized, fast library with JavaScript features that works across platforms and is quite useful. Firstly, JavaScript should be learned at a basic level and then a transition to the jQuery library should be made. If you are developing with JavaScript, you will surely use jQuery, so don’t rush.
