moment.duration().subtract(Number, String);
moment.duration().subtract(Number);
moment.duration().subtract(Duration);
moment.duration().subtract(Object);

Mutates the original duration by subtracting time.
The same keys and shorthands used to create durations can be used here as the second argument.
var a = moment.duration(3, 'd');
var b = moment.duration(2, 'd');
a.subtract(b).days(); // 1Note that adding an invalid duration to any other duration results in an invalid duration.
