DEBUG constant in TypeScript with UglifyJS

One of the requested features in TypeScript is support for the kind of compilation constants that C#, for example, provides, where you can say

#if(DEBUG)
  MessageBox.Show(...);
#endif

	// Modifiers on primary constructor params would be nice :-)
	struct Point(private readonly double x, private readonly double y)
	{
	[DestructuringPosition(0)]
	public double X { get; } = x;

	[DestructuringPosition(1)]
	public double Y { get; } = y;
	}

	class Bobbins
	{
	[CallStackLocal]
	public static string Value = "Foo";

	public static void Write()
	{
	Console.WriteLine(Value);
	}
	}
