operator >> method
Returns an Set that has been removed by the number of count
from the
end.
If count
is negative it throws
ArgumentError.
It is not in the Kotlin collection library. But I added it because it looks useful.
Implementation
Set<E> operator >>(int count) => count.isNegative
? throw ArgumentError.value(count, 'count', 'Cannot be negative')
: count > length
? {}
: take(length - count).toSet();
