-
-The `PlainWords` method on a `Page` object calls the [`Plain`] method, then uses Go's [`strings.Fields`] function to split the result into words.
-
-{{% note %}}
-_Fields splits the string s around each instance of one or more consecutive white space characters, as defined by [`unicode.IsSpace`], returning a slice of substrings of s or an empty slice if s contains only white space._

-{{% /note %}}
-
-As a result, elements within the slice may contain leading or trailing punctuation.
-
-```go-html-template
-{{ .PlainWords }}
-```
-
-To determine the approximate number of unique words on a page:
-
-```go-html-template
-{{ .PlainWords | uniq }} → 42
