Suggestion

⭐ Suggestion

• dropWhile(Lazy):
  Returns Iterable/AsyncIterable excluding elements dropped from the beginning. Elements are dropped until the value applied to f returns falsey.

• dropUntil(Lazy):
  Returns Iterable/AsyncIterable excluding elements dropped from the beginning. Elements are deleted until the value applied to f returns truly. (It is deleted including the value applied as true.)

💻 Use Cases

const dropWhileIter = dropWhile(a => a < 5, [1,2,3,4,5,6,7,8,9,10]);
dropWhileIter.next(); // 5
dropWhileIter.next(); // 6
dropWhileIter.next(); // 7
dropWhileIter.next(); // 8
dropWhileIter.next(); // 9
dropWhileIter.next(); // 10

const dropUntilIter = dropUntil(a => a > 5, [1,2,3,4,5,6,7,8,9,10]);
dropUntilIter.next(); // 7
dropUntilIter.next(); // 8
dropUntilIter.next(); // 9
dropUntilIter.next(); // 10
