Arduino delayMicroseconds equivalent

I've been "porting" an Arduino code example and been successfully converting it so far (not much to change other than removing the datatypes) and the code uses delayMicroseconds. Is there a similar way to achieve this in Espruino?

The code is basically:

method() {
  digitalWrite(pin, 1);
  delayMicroseconds(350);
  digitalWrite(pin, 0);
  delayMicroseconds(350);
}
