So, the interpolation of variable variable into some string may look like "<prefix>\{variable}<suffix>" Formatting also has formatting options. It may look like "<prefix>\{variable[:<options>]}<suffix>" Examples of options v := 123.45 fmt.Println("value=\{v:04.3}") // value=0123.4...
String Interpolation In Messages In some other cases where you want to handle further possible variants of a message, you can assign placeholder variables that can handle some specific cases of linguistic features. For instance, in the previous example where we used the plural can be written as:...
