How to Call Go Methods Within HTML/Templates?

Involving Go Methods in HTML/Template Interactions

Let's consider the following:

type Person struct {
  Name string
}
func (p *Person) Label() string {
  return "This is " + p.Name
}

How do we leverage this method within an HTML/template? A template such as this:

{{ .Label() }}

Method Invocation in Templates

Avoid using parentheses when calling methods in templates. For instance:

tmpl, err := template.New("").Parse(`{{.Label}}`)
if err != nil {
    log.Fatalf("Parse: %v", err)
}
tmpl.Execute(os.Stdout, Person("Bob"))

This approach adheres to the documentation guidelines, which specify that methods returning a single value (or a value and an error) can be called within templates. If an error occurs during execution, it will be returned and the template execution will cease.
