How do you use jQuery's each() method to iterate over a collection of DOM elements?

Question

Aryan Kumar · Answer

In jQuery, the each() method is used to iterate over a collection of DOM elements and perform an action on each element. Here's an example of how to use the
each() method:
$('ul li').each(function(index) {
 console.log(index + ': ' + $(this).text());
});
In this example, we use the jQuery selector $('ul li') to select all
li elements that are children of a ul element. We then call the
each() method on the resulting collection of elements.
The each() method takes a callback function as its argument, which is called for each element in the collection. The callback function takes two arguments: the index of the current element in the collection, and a reference to the current element itself.
In the example above, we pass a callback function that logs the index of each 
li element in the console, along with its text content. The $(this) keyword is used to reference the current
li element in the callback function.
Here are a few more things to keep in mind when using the each() method in jQuery:
You can break out of the each() loop at any time by returning
false from the callback function.You can access the length of the collection of elements using the length property. For example:
$('ul li').length.You can use the this keyword in the callback function to access the current element without having to wrap it in a jQuery object. For example:
$(this).text() is equivalent to this.textContent.
By using the each() method in jQuery, you can easily iterate over a collection of DOM elements and perform actions on each element as needed.
