Function map

map<T, U>(
iterable: ReverseSizedIterable<T>,
f: (x: T, i: number) => U,
): ReverseSizedIterable<U>
Maps over an iterable using a projection.

The projection must be a pure function, otherwise iterating in reverse will not yield the same items as iterating forwards.
Type Parameters
- T
  type of the item
- U
  type of the projected result
Parameters
- iterable: ReverseSizedIterable<T>
  the iterable
- f: (x: T, i: number) => U
  the projection
Returns ReverseSizedIterable<U>
- Defined in src/map.ts:29
map<T, U>(iterable: ReverseIterable<T>, f: (x: T) => U): ReverseIterable<U>
Maps over an iterable using a projection.

The projection must be a pure function, otherwise iterating in reverse will not yield the same items as iterating forwards.

When called with this overload, the index is not available.
Type Parameters
- T
  type of the item
- U
  type of the projected result
Parameters
- iterable: ReverseIterable<T>
  the iterable
- f: (x: T) => U
  the projection
Returns ReverseIterable<U>
- Defined in src/map.ts:47
map<T, U>(
iterable: SizedIterable<T>,
f: (x: T, i: number) => U,
): SizedIterable<U>
Maps over an iterable using a projection.
Type Parameters
- T
  type of the item
- U
  type of the projected result
Parameters
- iterable: SizedIterable<T>
  the iterable
- f: (x: T, i: number) => U
  the projection
Returns SizedIterable<U>
- Defined in src/map.ts:60
map<T, U>(iterable: Iterable<T>, f: (x: T, i: number) => U): Iterable<U>
Maps over an iterable using a projection.
Type Parameters

Parameters

  the iterable
- f: (x: T, i: number) => U
  the projection
Returns Iterable<U>
