How it works...

Go has two template packages--text/template and html/template. These share functionality and a variety of functions. In general, use html/template to render websites and text/html for everything else. Templates are plain text, but variables and functions can be used inside of curly brace blocks.

The template packages also provide convenience methods to work with files. The example creates a number of templates in a temporary directory and then reads them all with a single line of code.

The html/template package is a wrapper around the text/template package. All of the template examples work with the html/template package directly, using no modification and only changing the import statement. HTML templates provide the added benefit of context-aware safety. This prevents things such as JavaScript injection.

The template packages provide what you'd expect out of a modern template library. It's easy to combine templates, add application logic, and ensure safety when emitting results to HTML and JavaScript.
