lastElementAsync() Function

Returns the last element in array whose value satisfies the predicate.

Signature

export declare function lastElementAsync<T>(array: readonly T[], predicate: (value: T, index: number, array: readonly T[]) => PromiseLike<boolean>): Promise<T | undefined>;

Parameters

Parameter	Type	Description
array	readonly T[]	The array to search.
predicate	(value: T, index: number, array: readonly T[]) => PromiseLike<boolean>	A predicate. There should exist some index `I` such that `predicate(array[i])` returns true for all `i <= I` and returns false otherwise.
(Returns)	Promise<T \| undefined>	A promise that resolves to the last element in `array` whose value satisfies the `predicate`, or `undefined` if no such element exists.
