`dict` is especially useful for passing more than one value to a partial template.

`first` works in a similar manner to the [`limit` keyword in SQL][limitkeyword]. 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`

{{ range first 10 .Pages }}
```go-html-template
{{ range first 5 .Pages }}
{{ .Render "summary" }}
{{ end }}
{{< /code >}}
```
*Note: Exclusive to `first`, LIMIT can be '0' to return an empty array.*
Set `N` to zero to return an empty collection.
## `first` and `where` Together
```go-html-template
{{ $emptyPageCollection := first 0 .Pages}}
```
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:
