Type can be omitted
Reports types in variable and constant declarations that can be omitted since they can be inferred by the compiler. Such types are redundant, omitting them may improve readability of the code.
var s string = fmt.Sprintln("hi")
string type in the variable declaration may be omitted. To remove the type, use the Delete type quick-fix. After the quick-fix is applied:
var s = fmt.Sprintln("hi")
