Is the following sketch better?

#include <Servo.h>
Servo myservo;
unsigned long previousMillis = 0;
const unsigned long interval = 1000;
byte n = 0;

void setup()
{
  myservo.attach(9);  //signal pin is with DPin-9
  myservo.write(0);    //0 degree position
}

void loop()
{
  unsigned long presentMillis = millis();
  if (presentMillis - previousMillis >= interval)
  {
    previousMillis = presentMillis;
    if (n < 180)
    {
      n = n + 2;
      myservo.write(n);
    }
    else
    {
      myservo.write(0);
      n = 0;
    }
  }
}
