[toStringTag]: string

Methods

[dispose]

  • [dispose](): void

  • Returns void

  • [dispose](): void

  • Returns void

[iterator]

drop

  • drop(count): IteratorObject<T, undefined, unknown>

    Parameters

    • count: number

      The number of values to drop.

    Returns IteratorObject<T, undefined, unknown>

  • Determines whether all the members of this iterator satisfy the specified test.

    Parameters

    • predicate: ((value: T, index: number) => unknown)

      A function that accepts up to two arguments. The every method calls the predicate function for each element in this iterator until the predicate returns false, or until the end of this iterator.

        • (value, index): unknown

        • Parameters

          • value: T

          Returns unknown

    Returns boolean

filter

  • filter<S>(predicate): IteratorObject<S, undefined, unknown>

  • Creates an iterator whose values are those from this iterator for which the provided predicate returns true.

    Type Parameters

    • S

    Parameters

    • predicate: ((value: T, index: number) => value is S)

      A function that accepts up to two arguments to be used to test values from the underlying iterator.

        • (value, index): value is S

        • Parameters

          • value: T
          • index: number

          Returns value is S

    • S

    Parameters

    • predicate: ((value: T, index: number) => value is S)

      find calls predicate once for each element of this iterator, in order, until it finds one where predicate returns true. If such an element is found, find immediately returns that element value. Otherwise, find returns undefined.

  • Creates an iterator whose values are the result of applying the callback to the values from this iterator and then flattening the resulting iterators or iterables.

    Type Parameters

    • U

    Parameters

    • callback: ((value: T, index: number) => Iterator<U, unknown, undefined> | Iterable<U, unknown, undefined>)
