Also, consider making the array more specific, something like `array<String>`, or `String[]`. This check compares the return type specified in the `@return` annotation of a function or method doc comment with the types returned by the function and raises an issue if they mismatch. If the return type contains the type array, this check recommends the use of a more specific type like `String[]` or `array<String>`. Loading history...
