How does jQuery chaining work?

jQuery chaining allows you to perform multiple operations on the same set of elements in a single statement. It works by returning the original jQuery object after each method call, which allows you to call another method on the same object in a chain.

Here’s an example of how chaining works in jQuery:

// selecting all paragraphs, hiding them, and then showing them with a fade-in animation
$('p').hide().fadeIn();

In this example, the $('p') selector selects all paragraphs on the page and returns a jQuery object that represents them. The hide() method is then called on this object, which hides all the selected paragraphs. The hide() method also returns the same jQuery object, allowing you to call the fadeIn() method on it in the same statement. The fadeIn() method then shows all the selected paragraphs with a fade-in animation.

By using chaining, you can perform multiple operations on the same set of elements in a concise and readable way. However, it’s important to note that excessive chaining can make your code harder to read and maintain, so it’s best to use it judiciously.
