Ignoring values
Sometimes you need to ignore a value. Go provides the blank identifier _ for this. It's a write-only variable that discards whatever you assign to it.
_, err := someFunction()
This calls someFunction, ignores its first return value, and keeps only the error. The blank identifier lets you satisfy Go's "no unused variables" rule when you don't need a value.
