In Go, string concatenation is the process of joining multiple strings together into a single string. This can be done using the + operator, like so:
str := "Hello " + "world"

String interpolation, on the other hand, is the process of inserting variables or expressions into a string. In Go, string interpolation is accomplished using the fmt.Sprintf() function, which allows you to insert values into a format string using placeholders:
name := "Alice"
age := 30
greeting := fmt.Sprintf("Hello, my name is %s and I am %d years old", name, age)

In this example, the %s and %d placeholders are replaced with the values of the name and age variables, respectively. The resulting string is stored in the greeting variable.
So, while string concatenation simply combines strings, string interpolation allows you to insert values into a string and format it in a particular way.
