`delimit` called in your template takes the form of
```
{{ delimit array/slice/map delimiter optionallastdelimiter}}
```
`delimit` loops through any array, slice, or map and returns a string of all the values separated by a delimiter, the second argument in the function call. There is an optional third parameter that lets you choose a different delimiter to go between the last two values in the loop.
To maintain a consistent output order, maps will be sorted by keys and only a slice of the values will be returned.
The examples of `delimit` that follow all use the same front matter:
{{< code file="delimit-example-front-matter.toml" nocopy="true" >}}
+++
title: I love Delimit
tags: [ "tag1", "tag2", "tag3" ]
+++
{{< /code >}}
{{< code file="delimit-page-tags-input.html" >}}
<p>Tags: {{ delimit .Params.tags ", " }}</p>
{{< /code >}}
{{< output file="delimit-page-tags-output.html" >}}
<p>Tags: tag1, tag2, tag3</p>
{{< /output >}}
Here is the same example but with the optional "last" delimiter:
{{< code file="delimit-page-tags-final-and-input.html" >}}
Tags: {{ delimit .Params.tags ", " ", and " }}
{{< /code >}}
{{< output file="delimit-page-tags-final-and-output.html" >}}
<p>Tags: tag1, tag2, and tag3</p>
{{< /output >}}
