I need this c# code in javascript

Here is the c# code which needs to be converted to javascript:

List savedNumbers = new List();

else if (opperator == "M") { savedNumbers.Add(result); } else if (opperator == "P") { Console.WriteLine("Saved numbers:"); for (int i = 0; i < savedNumbers.Count; i++) { Console.WriteLine($"{i + 1}: {savedNumbers[i]}"); } } else if (opperator.StartsWith("R")) { int index; if (int.TryParse(opperator.Substring(1), out index) && index > 0 && index <= savedNumbers.Count) { x = savedNumbers[index - 1]; } else { Console.WriteLine("Result does not exist at location."); } }
