-
-Without a [`return`] statement, the `partial` function returns a string of type `template.HTML`. With a `return` statement, the `partial` function can return any data type.

-[`return`]: /functions/go-template/return
-
-In this example we have three partial templates:
-
-```text
-layouts/
-└── partials/
-    ├── average.html
-    ├── breadcrumbs.html
-    └── footer.html
-```
-
-The "average" partial returns the average of one or more numbers. We pass the numbers in context:
-
-```go-html-template
-{{ $numbers := slice 1 6 7 42 }}
-{{ $average := partial "average.html" $numbers }}
-```
-
-The "breadcrumbs" partial renders [breadcrumb navigation], and needs to receive the current page in context:
-
-```go-html-template
-{{ partial "breadcrumbs.html" . }}
-```
-
-The "footer" partial renders the site footer. In this contrived example, the footer does not need access to the current page, so we can omit context:
-
-```go-html-template
-{{ partial "breadcrumbs.html" }}
-```
-
-You can pass anything in context: a page, a page collection, a scalar value, a slice, or a map. For example:
-
-```go-html-template
-{{ $student := dict 
-  "name" "John Doe" 
-  "major" "Finance"
-  "gpa" 4.0
-}}
-{{ partial "render-student-info.html" $student }}
-```
-
-Then, within the partial template:
-
-```go-html-template
-<p>{{ .name }} is majoring in {{ .major }}. Their grade point average is {{ .gpa }}.</p>
-```
-
-To return a value from a partial template, it must contain only one `return` statement, placed at the end of the template:
-
-```go-html-template
-{{ $result := "" }}
-{{ if math.ModBool . 2 }}
-  {{ $result = "even" }}
-{{ else }}
-  {{ $result = "odd" }}
-{{ end }}
-{{ return $result }}
-```
