The following shows `after` being used in conjunction with the [`slice` function][slice]:
```
{{ $data := slice "one" "two" "three" "four" }}
{{ range after 2 $data }}
{{ . }}
{{ end }}
→ ["three", "four"]
```
## Example of `after` with `first`: 2nd&ndash;4th Most Recent Articles
You can use `after` in combination with the [`first` function][] and Hugo's [powerful sorting methods][lists]. Let's assume you have a list page at `example.com/articles`. You have 10 articles, but you want your templating for the [list/section page][] to show only two rows:
1. The top row is titled "Featured" and shows only the most recently published article (i.e. by `publishdate` in the content files' front matter).
2. The second row is titled "Recent Articles" and shows only the 2nd- to 4th-most recently published articles.
{{< code file="layouts/section/articles.html" download="articles.html" >}}
{{ define "main" }}
<section class="row featured-article">
<h2>Featured Article</h2>
{{ range first 1 .Data.Pages.ByPublishDate.Reverse }}
<header>
<h3><a href="{{.Permalink}}">{{.Title}}</a></h3>
</header>
<p>{{.Description}}</p>
{{ end }}
</section>
<div class="row recent-articles">
<h2>Recent Articles</h2>
{{ range first 3 (after 1 .Data.Pages.ByPublishDate.Reverse) }}
<section class="recent-article">
<header>
<h3><a href="{{.Permalink}}">{{.Title}}</a></h3>
</header>
<p>{{.Description}}</p>
</section>
{{ end }}
</div>
{{ end }}
