What will I learn in a jQuery course?

You can learn selectors, DOM traversal, element manipulation, events, effects, forms, AJAX requests, and plugin usage.

Do I need to know JavaScript before learning jQuery?

Basic JavaScript knowledge is recommended because jQuery is a JavaScript library, but beginners can learn foundational concepts alongside it.

How does jQuery select HTML elements?

jQuery uses CSS-style selectors, such as $('#id'), $('.class'), and $('p'), to find and work with page elements.

Can jQuery be used for AJAX?

Yes. jQuery provides methods such as $.ajax(), $.get(), and $.post() to send asynchronous requests and update pages without reloading.
