removeLastOrElse

function Array.removeLastOrElse<T, U>(
    target: readonly T[],
    value: NoInfer<T>,
    orElse: (target: readonly NoInfer<T>[]) => U,
): T[] | U

Removes the last occurrence of value from target array. If the value is not found, calls the orElse function with the original array and returns its result.

Example

data-first

import { Array } from "@monstermann/array";

Array.removeLastOrElse([1, 2, 3, 2], 2, () => []); // [1, 2, 3]
Array.removeLastOrElse([1, 2, 3], 4, (arr) => arr); // [1, 2, 3]

data-last

import { Array } from "@monstermann/array";

pipe(
    [1, 2, 3, 2],
    Array.removeLastOrElse(2, () => []),
); // [1, 2, 3]

pipe(
    [1, 2, 3],
    Array.removeLastOrElse(4, (arr) => arr),
); // [1, 2, 3]
