children().eq(1

`children().eq(1)` is a jQuery method that selects the second child element of the selected parent element.

Here's how it works:
- `children()` selects all the direct child elements of the selected parent element.
- `eq(1)` selects the second element from the collection of selected child elements. Note that the index is zero-based, so `eq(0)` would select the first child element.

For example, if you have a parent element with three child elements like this:

<div id="parent">
  <p>First child</p>
  <p>Second child</p>
  <p>Third child</p>
</div>

You can use `children().eq(1)` to select the second child element like this:

$('#parent').children().eq(1); // selects the <p> element with "Second child" text
