jQuery first and last methods

There are also separate methods first and last to select the first and last element of a set.

Let's consider the work of the above methods using the following paragraphs as an example:

<p>text</p>
<p>text</p>
<p>text</p>

Let's find all the paragraphs, then select the first one from those found and assign it the text '!':

$('p').first().text('!');

Now, let's choose the last one from the found ones and give it the text '!':

$('p').last().text('!');

Find the first li in the set and color it red.

Find the last li in the set and color it green.
