What is blank import in Golang?
To suppress the “unused import” error we would otherwise encounter, we must use a renaming import in which the alternative name is _ , the blank identifier.
As usual, the blank identifier can never be referenced.

What are identifiers in Golang?
In programming languages, identifiers are used for identification purposes.
In other words, identifiers are the user-defined names of the program components.
In the Go language, an identifier can be a variable name, function name, constant, statement label, package name, or type.
In place of div identifier just use the _ (underscore).
It allows the compiler to ignore declared and not used error for that particular variable._{30 août 2022}

Can a blank identifier have any value?

The blank identifier can ignore any value.
The main use cases for this identifier is to ignore some of the values returned by a function or for import side-effects._{23 jan. 2020}

The _ (underscore) is known as the blank identifier in Go. We can use the blank identifier to declare and use the unused variables. The unused variables are the variables that are only defined once in the program and not used.
