It provides CSS kind of selectors which allows you to select multiple components in one go and modify them in just one line of code e.g. you can grab all buttons and enable or disable them, just like we did in this example.
Now, coming back to the free jQuery courses to learn online. I personally find an online course best for learning a new framework or library, followed by a good book.
There are also cases where a free course on Udemy changed to paid courses once the instructor hit their promotion target, so you better check out before enrolling on them.
Also, I suggest you enroll sooner than later even if you don't have time to learn jQuery right now but want to learn in near future because once you enrolled in the course you get it free for a lifetime and you can learn it anytime
This is one of the latest course to learn jQuery and jQuery UI and a good place to start if you are learning jQuery this year. It has already got more than 9000 students and it's still free, but may not remain so forever.
The course is divided into two sections, jQuery Introduction, and the jQuery UI introduction.
In the first section, you will learn what is jQuery and how to use it followed by downloading the jQuery library.
In jQuery introduction section, you will learn about essential jQuery concepts like selectors, filters, replacing contents, handling events and some basic animation effects like fading, sliding, toggle, hide and show etc.
The jQuery UI section focuses on essential jQuery UI widgets like DatePicker Widgets, Tooltip Widgets, Accordion Widgets, and Tabs Widgets.
Overall, a good introductory course for anyone who wants to learn jQuery this year. Though, prior experience with HTML and CSS is desired, which you can get by joining free frontend web development courses I have shared earlier.
If you don't know jQuery is divided into two libraries, jQuery, and jQuery UI. JQuery is all about validation, selector, and DOM manipulation while jQuery UI provides several cool UI widgets which you can use in your web application.

This is another free course to learn jQuery by creating responsive websites using HTML, CSS, and Bootstrap.
Later it uses BootStrap, a CSS library for styling to style the web pages. BootStrap helps to create responsive images forms, menu, links and using font awesome icons with bootstrap etc.
In the last section, you will learn jQuery to provide animation and targeting page elements using class and id selector.
You will learn about adding and removing CSS classes from a group of elements using jQuery, changing HTML text, closing and targeting parent and child elements etc.
In short, a good hands-on course to learn the practical aspect of jQuery by doing a full project using HTML, CSS, and jQuery. It's also quite popular and more than 13,300 students are enrolled in this course with 435 ratings at an average of 4.1

This is a very good course to learn jQuery from scratch. It's a beginner level course but you will learn most of the things you need to develop a compelling user interface using jQuery.
This course will teach you how to use different jQuery selectors e.g. id, class, and tag selectors to select and manipulate DOM elements, handling events and applying animation to create a responsive user interface.
It also provides comprehensive coverage of jQuery selectors and interacting with DOM e.g. iterating through nodes, modifying individual properties and attributes, adding and removing nodes, modifying style like adding/removing CSS selectors etc.
Apart from API and functions you will also learn how jQuery works and some essential concepts like why using CDN is better for downloading jQuery library and working with AJAX features like loading HTML content from the server and understanding load(), get(), post() and ajax() function.
Btw, if you like free resource than let me tell you that I have been sharing a lot of free resources in this blog from quite sometime like free courses and books on Spring, Python, REST, Jenkins, JUnit, Docker, PHP, React, Web Development, and many more.
