Question

Go's text/template package provides a way to generate dynamic text output by defining templates that contain placeholders for dynamic data. A template is a string that contains placeholders for values that will be filled in at runtime. The text/template package provides a way to fill in these placeholders using data from Go variables.
Templates are created using the template.New() function or the Parse() function, which take a string that defines the template. Placeholders are denoted by double curly braces ({{ }}), and can contain expressions that will be evaluated at runtime.
Once a template has been defined, it can be executed using the Execute() function, which takes a writer and a data object as parameters. The data object is a Go variable that contains the data that will be used to fill in the placeholders in the template.
In addition to placeholders, templates can contain control structures such as loops and conditionals, as well as function calls to custom functions that can be defined by the programmer. This allows for complex dynamic output to be generated based on the data provided.
The text/template package also provides a html/template package, which is a variant of the text/template package that is specifically designed for generating HTML output. This package includes additional security features to prevent common web security vulnerabilities such as cross-site scripting (XSS) attacks.
Overall, the text/template package provides a flexible and powerful way to generate dynamic text output in Go, making it a useful tool for building web applications, generating reports, and more.
