Function size

size<T>(input: Set<T> | Map<unknown, T> | T[]): number
Returns the number of elements in any iterable structure.

For AsyncIterable returns Promise<number> (full traversal). For Array, Set, Map, Record uses native length/size/key count.
Type Parameters
- T
Parameters
- input: Set<T> | Map<unknown, T> | T[]
Returns number
- Defined in src/iterable.ts:838
