Learned about functions in Go templates.

Functions in Go templates help you perform different operations on the data you're working with, making your templates more flexible and powerful

• Here you can create your own custom function
• use the built-in function provided in the go template packages

keep in mind

// fm is a FuncMap containing template functions. // "psw" is a custom template function key that maps to the pickSecondWord function var fm = template.FuncMap{ "psw": pickSecondWord, }

func init() { tmpl = template.Must(template.New("").Funcs(fm).ParseFiles("tmpl.gohtml"))

}

// ExecuteTemplate executes the template and print the result to the standard output. err := tmpl.ExecuteTemplate(os.Stdout, "tmpl.gohtml", data)

if err != nil {
	panic(err)
}
