first works in a similar manner to the limit keyword in SQL. It reduces the array to only the first N elements. It takes the array and number of elements as input.

first takes two arguments:

1. number of elements
2. array or slice of maps or structs

{{< code file="layout/_default/section.html" >}} {{ range first 10 .Pages }} {{ .Render "summary" }} {{ end }} {{< /code >}}

Note: Exclusive to first, LIMIT can be '0' to return an empty array.

first and where Together

Using first and where together can be very powerful. Below snippet gets a list of posts only from main sections, sorts it by the title parameter, and then ranges through only the first 5 posts in that list:

{{< code file="first-and-where-together.html" >}} {{ range first 5 (where site.RegularPages "Type" "in" site.Params.mainSections).ByTitle }} {{ .Content }} {{ end }} {{< /code >}}
