Templates are mainly used for separating the formatting and data parts of the output. Note that a Go template can be either a file or string: the general idea is to use strings for smaller templates and files for bigger ones.
In this section, we will talk about the html/template package by showing an example, which can be found in the template.go file and will be presented in six parts. The general idea behind template.go is that you are reading a text file with records that you want to present in HTML format. Given that the name of the package is html/template, a better name for the program would have been genHTML.go or genTemplate.go.
