        let email = self
        let components = email.components(separatedBy: "@")
        var maskEmail = ""
        if let first = components.first {
            maskEmail = String(first.enumerated().map { index, char in
                return [0, 1, first.count - 1, first.count - 2].contains(index) ? 
char : "*"
            })
        }
        if let last = components.last {
            maskEmail = maskEmail + "@" + last
        }
        return maskEmail
    }


  var maskPhoneNumber: String {
    return String(self.enumerated().map { index, char in
        return [0, 3, self.count - 1, self.count - 2].contains(index) ? 
    char : "*"
    })
     }
